How to cut foam block with a hand saw. Bulgarian

Magazine “Designer

Foam blocks are used in construction very often. They resist the heat well, have light weight, voluminous, and also very easy to process.

They can not only be sawed, chopped off, drilled, and also processed even a shirt, chisel and other tools.

We highlight the main tools with which you can cut foam blocks:

Hand saw

Such a saw is used in the construction of small facilities (country house, economic construction, garage, etc.) where a large number of foam blocks are not required.

However, it is worth considering what to saw, if the density of foam blocks is large, it is better, of course, use an electric tool.

Do not be afraid of a hand saw, if you work carefully and carefully, then you can cut without irregularities and chips, and you can also cut out figured elements.

However, it must be remembered that foam blocks are a special building material, you need to work carefully with it. When sawing, it tends to crumble! No need to put pressure on the tool! Drinking with a hand saw only absolutely dry material.

Sprinking, as a rule, is better and easier by pre.Made marks. The position of the saw should be at an angle of 45 degrees. The saw should be long, so that on the finish line, the unproved residue does not break and does not fall off, spoiling the cut.

Electric jigsaw

Masters know such a jigsaw as a saber’s saw. This saw is used in the construction of medium and large facilities.

On the jigsaw you can change the blades (put wheels with different sizes of teeth, change the blurted or spoiled discs; the shape of the cloves on the disks can also be different. Large and small teeth).

As a rule, for the convenience of builders, many models of saws are produced with interchangeable batteries so as not to be attached to the power source.

When working with this type of tool, it must be remembered that cutting wet material is not permissible, this may entail injury. Saw “rinses” crumbs and can injure the builder.

Before starting work, it is better to try on the tool. Lose a saw with a saw without on food.

It is necessary to cut the middle part of the saw, the length of the working cutting surface should be approximately 25 centimeters.

In order not to be injured, you should hold the saw tightly in your hands.

Alligator

A alligator.Type saw has a special strength and wear resistance. On the cloves of such a saw there are special surfaces from winning, which makes the teeth more durable. Such a tool is used in the construction of large facilities (apartment buildings, large.Area offices).

The plus of this tool is that it does not need to constantly sharpen or change the blades, as, for example, in an electric jigsaw.

When buying such a saw, it is better to choose an option with a thick.Walled blade, since only saw such a blade will give an even cut without chips and roughnesses.

Often they write that before starting work with such a saw, you need to lubricate the surface with a special lubricant, but practice talks about the opposite. The lubricant is mixed with dust, as a result of which the saw may stop working.

Although in the instructions for most tools of this type, the use of grease is spelled out. The lack of lubricant increases the productivity of work at times.

Most often used in the construction of household objects of small area. Sprinking is gradually made according to pre-made marginal marks.

It is also used in domestic conditions. Often used if you need to get an U-shaped shape of blocks. Since a lot of dust rises when working with a grinder, you should not neglect the bug and other means of protection.

Some home masters saw foam blocks with an ordinary saw that saw a tree. This method is fast and quite effective, but the chains are quickly dull, and sometimes even break and jammed.

In addition, with a cut, such a saw forms a very large amount of harmful dust. Therefore, if you plan to saw in this way, be sure to protect the breathing organs from dust.

When choosing a tool for cutting aerated concrete, you do not need to chase the cheapness. As a rule, cheap. Does not mean reliable. However, it is better to rely not on your intuition, especially if there is no experience in such a matter, but to read reviews or talk with knowledgeable people.

Usually people without experience who want to build a small object for themselves opt for a manual tool. Firstly, it is cheaper, and secondly, it’s easier to work with it. People with experience prefer a more complex tool. Electric.

The basics of processing aerated concrete blocks with saws

Masters who have more experience in communicating with construction electric equipment and devices, as well as the need to work with them more often, prefer to cut aerated concrete bricks with an electric saber or a saw-alegator, and not a manual tool. But with a one.Time use of aerated concrete (for example, when erecting a outbuilding, garage or a summer house. They do not need them a few on one site) a manual saw for aerated concrete will be more economical and more reliable.

  • Electric saber saw on aerated concrete is a powerful electrician that gives the cutting canvas in the form of sabers horizontal reciprocating movement. There are saws with two lips-lines, many models work from the battery. Fabric for a saber saw are sold with teeth of different sizes and shapes.
  • The Alligator’s saw works on the principle of the crankshaft-the rotation of the electric motor rotor turns into the reciprocating movements of two cutting paintings. The blades are moved in opposite directions, but in the horizontal plane, so the cut of the cut is always clean and even. The price of such a power tool is much higher than that of a saber saw, and the Alligator saw will justify itself only with constant use, that is, in professional construction. Therefore, before such a highly specialized purchase, think about where this tool will work after the construction is completed.
  • A manual saw with carbide (winning) attacks on teeth serves much longer than a regular hand saw, which after a few cuts have to be sharpened. On the winning attacks you can build a house without replacing the saw, and it will still serve further. When choosing such a tool, it is recommended to pay attention to the thickness of the canvas. The thin saw will take aside, the cut will turn out uneven and inclined. A saw with a thick canvas makes an accurate, neat and even cut.

Therefore, when choosing how to saw aerated concrete, pay attention to the accuracy and reliability of the tool, and not to its price: many people think that an expensive power tool is the key to successful construction, but this is not always the case. First try to cut the foam block with a regular hand saw, and only with unsatisfactory results buy more expensive saws on aerated concrete.

Other tools for working with foam blocks

How to cut foam block so that each element has a perfectly smooth surface?

This requires another tool. Shirts for cellular concrete. Small metal files with small teeth are fixed at a wooden block at an angle. With such a device it is easy to align the surfaces of the cut block.

About the types of hacksaw cutting foam concrete

Before choosing a hacksaw according to aerated concrete, you need to find out what kind of species are. Devices differ according to the following criteria:

  • Type of drive. Manual, electric and gasoline. What kind of hacksaws of aerated concrete have an outwardly understandable, and electric and gasoline are electric and chainsaws (as well as disc saws and grinder), on which before the work you need to install a saw chain with winning attacks or wheels
  • By type of canvases, these are sabers for hand tools, as well as tape and disk for automatic units

If there is a chainsaw or electric saw on the farm, then for working with aerated concrete you will only need to buy a special chain with attacks from winnet on teeth. However, the cost of such a chain is 2-3 times more than the price of a wood chain, so you can judge the rationality of such a purchase yourself. If there is a need to purchase a chain on a chainsaw with a winning attack for cutting concrete, then you can do this in an online store for the sale of construction equipment.

Manual hacksaws are produced by different types, and they differ in such indicators:

  • The length of the paintings. A hand tool is released with the dimensions of paintings from 50 to 70 cm. It is better to buy equipment with a long canvas, which will allow you to produce not only the transverse, but also the longitudinal cut of the materials
  • The thickness of the canvas is the thicker, the better, but even more expensive the tool itself. Thick canvases do not bend and are not deformed during sawing, so the cut is flat, straight and without distortions. To receive even drink, it is recommended to use a corner template or a square
  • Canvas material. For this, alloy and stainless types of steel are used. These have become so durable that the tool can be used to cut shell
  • The presence of attacks on the teeth. If you want the equipment to serve for a long time, then the presence of attack on the teeth is mandatory. As carbide materials, it is used not only to win (glorious cobalt with tungsten), but also by Rapid, monocarbide and others. The need to use silver spraying is absent

In these indicators, the hand.Made tools are considered from each other. If it is planned to carry out work with your own hands, then it is better to choose a hand saw on foam concrete not cheap, otherwise physical fatigue will quickly arise.

Classification of hacksaws

Careboods are divided into several types: on wood, metal, aerated concrete (foam concrete) and drywall. Such a division is due to the fact that the saws that differ in the teeth, as well as the shape of the tool, are designed for different works. For example, a wood hacksaw can cut not only wood, but also aerated concrete and drywall. And the metal tool cuts metal, but it is capable of cutting and all other materials.

On wood

You need to approach the purchase of a hacksaw on wood carefully. They differ from each other in the shape of saws, handles, varieties of teeth

Classic hacksaw is also called ordinary or wide. This saw cuts wooden things along or across. Triangular teeth of a saw, the step between them is from 1.5 to 6.5 mm. The classic appearance quickly cuts wooden products, the only minus is that the thread itself is rough and there is a lot of chips, but for garden work is perfect.

Narrow (outfound). This is a specialized saw. The hacksaw can have teeth on both sides, which provides a more accurate cut. Such a tool is designed for thread when you need to carefully cut out wood parts.

The spike is designed for a neat cut when the cut is beautiful and there are not so many chips. The teeth of the hacksaw have the shape of an isosceles triangle. The saw is used only for transverse threads, the width of the tool is usually no more than 1-1.5 mm.

Types of woodcuts for wood are also divided depending on the shape of the teeth:

However, for the cut of the laminate, such a tool will not work. After 20 cuts it will be very difficult to work, as the teeth will already dull.

For metal

This is a type of saw, which is designed to cut metal structures. Such a tool can cut wood, aerated concrete, drywall, but is not able to cut stone and concrete.

It is better to use a hacksaw for metal, of course, for its intended purpose and cut only metal structures. The saw includes the following elements: a canvas for a hacksaw, fastening frame and a handle to hold a saw.

The tool canvas is unilateral or bilateral. The convenience of the bilateral canvas is manifested in the fact that the canvas of the saw on the metal wear out quickly, it is necessary to update it constant, and when there are two sides, this can be done less often.

When inserting the canvas into the frame for fastening, it is important to do this correctly, otherwise the speed of the saw will decrease, and thus you can break the saw. You can also adjust the angle of inclination for professional saws for metal and make it at 45, 90 or 180 degrees

By aerated concrete and foam concrete

To cut aerated concrete or foam concrete, you will need to buy specialized tools. Such saws have a certain design with winning attacks. The instrument teeth carry out more rigid cut into the surface of the material.

Khosuovka on aerated concrete is used for both longitudinal and transverse saw. Khosuvka in foam concrete are represented by three types of incisors:

  • 2-2.5 mm-used for small parts and neat threads;
  • 3-3.5 mm-used for medium sizes;
  • 4-6 mm-the product is large, difficult to cut.

By drywall

A hacksaw for drywall or a sprout hacksaw is used to cut this material and also cut out various holes. Such a saw is made of high.Quality steel, so it is almost impossible to break it.

The blade of the saw on drywall is thin, the length of the canvas does not exceed 20 cm, the tool has a convenient compact handle, so various parts are cut out with such a saw and do it carefully.

Application in construction

It is already known that with a hacksaw on foam block, it is possible to produce cuts of foam and aerated concrete blocks, as well as other similar building materials. This means that this hacksaw is used on construction sites in the construction of buildings, in construction in summer cottages, where foam concrete can be used.

You can work with such material using a strip or saber’s saw, a circular with a disk intended for this, but all these tools are expensive. They are used by organizations, brigades with large volumes of construction. For private use, the best option would be a manual saw on aerated concrete. The characteristic features of this tool do not allow it to use it to work with other materials, for example, with wood or metal. It is more advisable to use it only as intended.

Cutting foam concrete. Cutting technology for the manufacture of foam blocks

Pentate cutting technology

Cutting technology for the manufacture of foam blocks provides for pouring the foam concrete mixture into forms without cells with lightly removable formwork. Within 6-9 hours, foam concrete is gaining the necessary strength to remove formwork. After that, the foam concrete array on the pallet is transferred by a traverse to a cutting complex for cutting foam concrete.

The design of the complex for cutting foam concrete ensures the manufacture of foam blocks with an accuracy of 1 mm. Equipped with a pitch withdrawal and twisted strings for cutting a foam concrete massif. Penoboton cutting cycle is 5-7 minutes. String for cutting foam concrete can be installed on the required dimensions of foam blocks.

Thanks to the technology of cutting foam concrete, the manufacture of foam blocks with high accuracy of geometric sizes, straightness of the faces, excellent quality of surfaces. This, in turn, allows you to put foam blocks using glue, which significantly increases the heat efficiency of external walls from foam blocks.

Details about cutting equipment for the manufacture of foam blocks are indicated for equipment for the manufacture of foam blocks

  • The design simple for independent manufacture and consists of one metallic suction and one stable side suitable for any pallet. The rubber gasket glued to the bottom of the side provides tightness and quick assembly of shapes by one person;
  • Cleaning time. 2 min./ 1 person.
  • Assembly time. 1 min./ 1 person.
  • Lubrication time. 2 min./ 1 hour.
  • Time for falling off. 3 min./ 1 person.
  • Time for removing blocks. 2 minutes./ 1 person.

Cutting technology for the manufacture of foam blocks

Let us explain the technology of manufacturing foam blocks using foam concrete cutting:

  • Assembly of forms,
  • Lubrication of forms,
  • Fill the forms.
  • Ringing forms,
  • Penoboton cutting on foam blocks,
  • Drying foam blocks on pallets,
  • Assembly and lubrication of forms,
  • Fill the forms.
  • Ringing forms,
  • Penoboton cutting on foam blocks,
  • Drying foam blocks on pallets,
  • Removing blocks from pallets,
  • Assembly and lubrication of forms,
  • Fill the forms.

With cutting technology for the manufacture of foam blocks compared to casting technology:

  • The quality of the produced blocks improves,
  • The number of labor.Intensive operations is reduced,
  • The number of workers is reduced,
  • The cost of blocks is reduced,
  • The volume of manufacture of foam blocks and t increases.D.

Production of production according to costs is 75 %.

For this production, according to the requirements, 5-6 workers and 400 kV are enough.M. Square.

Thus, the key to successful production for the manufacture of foam blocks is the use of foam concrete cutting technology on modern cutting equipment manufacturing foam blocks:

Spilling techniques with a circular saw with and without devices, as well as what can be cut and how to properly use it

To work with a hand circular saw, special qualifications are not required. It is enough to try the first time, then for a few cuts the user will understand the possibilities of the tool: how quickly he saws, how to crush, so as not to “strangle” the engine, how the electric saw behaves when starting, how the cord is stretched so that it does not fall under the saw. This is about simple sawing, for example, firewood.

It is a little more difficult to make even cuts and achieve an accurate carpentry cut (plus/minus 1mm or degree). It is difficult to achieve more accuracy with such a tool, although in principle and possible. But such tolerances in most cases are permissible, taking into account the fact that wood is able to dry out and swell, changing the volume and size with a large amplitude (up to 10%). For jewelry accuracy, other tools are used, including hand hacksaws with a small tooth.

Secrets and nuances. Part two

Forumhouse users tell how to process aerated concrete blocks using electrical tools.

Recall our readers that in the first part of the material we told how to cut aerated concrete with a hand saw.

In addition to this method, FORUMHOUSE users have accumulated extensive experience in processing aerated concrete with an electric tool. As practice shows, this is the choice of those who need speed, the ability to quickly saw large volumes of aerated concrete or make complex elements.

What electric tool is best cutting aerated concrete

To answer this question, we turn to the table already known to us, where the results of the survey of our users are given.

As you can see, in second place after a manual saw is a saber saw equipped with a special peel on aerated concrete. Consider the nuances of working with this tool in more detail.

I am building a house made of aerated concrete in a seismic hazardous area. In the walls I make grooves for filling concrete columns, respectively, I have to saw a lot. I tried to cut aerated concrete D400 B2.5 hand.Saw with carbide attacks. It saws, of course, good, but still takes the strength and time. Planned to mechanize this process. Buy an ALGARA saw is expensive and irrational. I believe that a saber sawa gas concrete saw will be fixed the situation. It remains only to choose the right tool.

After studying the issue, PGorlov acquired a seable saw with a capacity of 1010 watts, which did not ruin the family budget, and a special canvas for a gas concrete 36.5 cm.

One day, tests of the tool began. Taking a gas concrete block, PGORLOV tried to cut it and was unpleasantly surprised by the negative result of the work. The saw was all the time, instead of sawing, the tool was beating with emphasis on the unit, as a result. The saw almost torn from his hands.

After thinking, because of what this could happen, the father-in-law of our user suggested that the block was raw, and we must try to cut dry. It went. Let it not as quickly as we would like, but a certain algorithm has been developed by trial and error, which allowed aerated concrete with success.

The saw does not need to be hard to put on the surface of the block. Keep the saw at a sufficient distance from the block, slightly shaking it according to the “Up-down” scheme, as if we sawed the block with a hand saw. We saw not the entire surface of the file, but about 25 cm. The block should be dry, then the saw does not pull the saw, and it does not vibrate.

If you saw with a saber’s saw, like a jigsaw, resting it with an emphasis on the end of the block, then dust, especially if the block is raw, sticks on the canvas and is bite. Using this option, Pgorlov sawed dozens of cubic meters of blocks, sawing aerated concrete along, across, throwing it on thin plates. It was possible to cut even blocks with a width of 50 cm, making cuts first from one, and then from the other side.

The result of the work: this set is not very dusty, it can not even be compared with the circular saw. Over, I drank mobile, it is convenient to work in constrained conditions. For example, when working in the attic, when clipping “sleeves” under a chimney made of aerated concrete or curly elements for filling columns.

The next most popular is the Alligator saw. The first part of the article describes the principle of its work. Based on the experience of our users, it was concluded that its purchase was justified in case of cutting large volumes, with a clear awareness. For which this professional tool is bought.

I had the next way to the “Alligator”. At first I sawed aerated concrete on a home.Made tape machine and, as a result, refused this method. It is inconvenient to use. The machine in one place, aerated concrete. In another, it must be dragged, laid on the table, etc.D. Began to saw with a manual saw, not bad, but slowly. As a result, I bought an alligator saw, I think it will be as convenient to saw it as a simple saw, but an order of magnitude faster.

User with the nickname Vic_v also saws aerated concrete “Alligator”. He advises not to lubricate the sawing parts of the saw, as the instruction prescribes. Dust sticks on grease (through specific holes), the lubricant disappears, the saw begins to saw the dry, and the tool jams. As a result, Vic_v dismantled the saw, wiped his lubricant, cleaned all the dust, collected the “alligator” again, and the saw earned it.

For 2 hours I drank 70 blocks (the length of the sawing 60 cm), dissolved them for formwork and shaped gutters above the Windows. Saws the saw perfectly, quickly, evenly, you can dissolve the blocks “hundred” vertically and along.

And I made a special device for “alligator”. A guide, which I fasten to the block with self.Tapping screws. The cut is very flat.

So, the Alligator saw saws smoothly and quickly, but it is expensive. Therefore, among the developers there are many who think. And what if you saw blocks of a circular or chain saw? Both the one and the other method have the right to life, but before you choose one of them, you need to find out a couple of nuances.

We saw aerated concrete with an ordinary endings on both sides and then finish it with a hand saw, so we have to turn the block.

I first drink a block from 4 sides with a circular with a backwood disk, and then I finish it manually. Contrary to expectations, the circular is still alive and works well, although I sawed it with blocks for a barn and a two.Story house.

Choosing a circular (however, like a “alligator”), we remember that the process of sawing aerated concrete will be dusty. Especially if you use the tool in a closed room. Therefore, do not forget to use protection. We put on glasses, the respirator, the dust remote system will not hurt.

Those who want to cut the block as quickly as possible, often opt for a chain saw. The high speed of the cut has a flip side. It cannot be guaranteed that the saw will withstand the load and will not break. Also, the consumption of the chains is concerned about everyone.

My workers sawed aerated concrete chainsaw. There were enough chains for two rows.

Alligator

A alligator.Type saw has a special strength and wear resistance. On the cloves of such a saw there are special surfaces from winning, which makes the teeth more durable. Such a tool is used in the construction of large facilities (apartment buildings, large.Area offices).

The plus of this tool is that it does not need to constantly sharpen or change the blades, as, for example, in an electric jigsaw.

When buying such a saw, it is better to choose an option with a thick.Walled blade, since only saw such a blade will give an even cut without chips and roughnesses.

Often they write that before starting work with such a saw, you need to lubricate the surface with a special lubricant, but practice talks about the opposite. The lubricant is mixed with dust, as a result of which the saw may stop working.

Although in the instructions for most tools of this type, the use of grease is spelled out. The lack of lubricant increases the productivity of work at times.

Household saw on a chain

Some home masters saw foam blocks with an ordinary saw that saw a tree. This method is fast and quite effective, but the chains are quickly dull, and sometimes even break and jammed.

In addition, with a cut, such a saw forms a very large amount of harmful dust. Therefore, if you plan to saw in this way, be sure to protect the breathing organs from dust.

When choosing a tool for cutting aerated concrete, you do not need to chase the cheapness. As a rule, cheap. Does not mean reliable. However, it is better to rely not on your intuition, especially if there is no experience in such a matter, but to read reviews or talk with knowledgeable people.

Usually people without experience who want to build a small object for themselves opt for a manual tool. Firstly, it is cheaper, and secondly, it’s easier to work with it. People with experience prefer a more complex tool. Electric.

Band-saw

The tool is a multi.Cut cutting machine. The cut is carried out by a circular steel ribbon, on one side having a teeth. The productivity of the strip saw is high. So, using the machine, you can quickly perform a foam concrete more quickly compared to a manual hacksaw.

Penusoblok sawing ribbon

A high.Tech alloy of solid metals is used for the guide canvas. The machine is indispensable for the construction of large facilities. The tape saw can be cut blocks of any width, since the height is regulated. A big advantage is that this saw copes with foam, aerated concrete of any type, independently is autoclave hardening or natural.

There are models that carry out the cut in a straight line and diagonals. The machine can be equipped with an automated homing function, which affects the accuracy of cutting concrete blocks. The guide videos allow you to increase the working resource of the strip saw, and the gaps of the cutting canvas, with which the waste is removed, ensure non.Stop work.

The strip saw is equipped with eye and wheels, which makes it possible to transport it. Additional stops in the machine contribute to sustainability during operation. There is also a system of dustyness, which during the operation of the machine immediately absorbs all dust.

How to cut foam blocks at home?

Often there is a need to fit the right size of foam block or gas block materials. This is determined by the conditions put forward during the design and work. It happens that a block of standard sizes does not become a designed place. To install only the required part, the material is sawn, and a hacksaw on foam concrete is used in this situation. Let us consider in more detail the features of the tool, the selection criteria.

The active use of cellular concrete in construction raises quite a few questions before those who chose them for building a house. Porous products are easy to process, they are simply cut with a manual or mechanical tool. If foam blocks are selected as a building material. How and how to cut you need to know in more detail.

How to cut cellular concrete

When calculating the foam blocks for the house, you can try to choose them in size so as to lay products without cutting. But this method is very laborious, and most likely it is unlikely to succeed.

Alligator

A alligator.Type saw has a special strength and wear resistance. On the cloves of such a saw there are special surfaces from winning, which makes the teeth more durable. Such a tool is used in the construction of large facilities (apartment buildings, large.Area offices).

The plus of this tool is that it does not need to constantly sharpen or change the blades, as, for example, in an electric jigsaw.

When buying such a saw, it is better to choose an option with a thick.Walled blade, since only saw such a blade will give an even cut without chips and roughnesses.

Circular

Most often used in the construction of household objects of small area. Sprinking is gradually made according to pre-made marginal marks.

Bulgarian

It is also used in domestic conditions. Often used if you need to get an U-shaped shape of blocks. Since a lot of dust rises when working with a grinder, you should not neglect the bug and other means of protection.

Some home masters saw foam blocks with an ordinary saw that saw a tree. This method is fast and quite effective, but the chains are quickly dull, and sometimes even break and jammed.

In addition, with a cut, such a saw forms a very large amount of harmful dust. Therefore, if you plan to saw in this way, be sure to protect the breathing organs from dust.

Usually people without experience who want to build a small object for themselves opt for a manual tool. Firstly, it is cheaper, and secondly, it’s easier to work with it. People with experience prefer a more complex tool. Electric.

Hand tool

The easiest and cheaper will be the use of manual tools. But it is suitable only for small volumes of work.

Manually easily easily cut the elements to fit the door and window openings, the device of the walls of the walls. Foam blocks with a hand tool is distinguished by maneuverability of operations, ease of execution.

For greater accuracy of working with hand tools, you will also need:

The following tools are suitable for this:

  • Krywalk will help if the cuts are required by several blocks. With large volumes of work, the tool will often need to sharpen, which is quite laborious. In addition, it is hard to work with such a device.
  • A special manual saw for cutting porous materials differs from the usual hacksaw with a larger metal thickness. Due to this, it bent less. The saw also has a special spraying or attack of solid alloy on large teeth. Tools are made with one or two handles. The canvas is performed different lengths.

A more effective option will be the use of a mechanized tool.

Electric tool

The power tool has much greater performance than manual. If the volume of work performed is quite large, then the use of mechanized cutting will be more effective.

  • Sable electric saw is well suited for not very large in terms of work. The principle of its action is similar to the usual electronics. It works from the mains.
  • The strip saw is a tape, on one side of which steel teeth are fixed. She produces the cut much faster and more precisely than manual devices.
  • Diamond disks. An angular grinding machine (Ushm), when cutting foam blocks, creates a large amount of dust and noise. This leads to the need for constant cleaning of the tool so that it does not overheat. In addition, when working with it, personal protective equipment will be required.

Note: but the use of a grinder is possible when cutting niches, an increase in window and doorways in the finished walls. For these purposes, use disks with a diameter of 30 cm. Dust collection is better to carry out an industrial vacuum cleaner.

  • Cable or string equipment for cutting light concrete also requires the possibility of connecting to the mains. For its operation, running water is needed. String for cutting foam blocks are metal cables with the inclusion of diamond elements. Perlin.

The price of such equipment is quite high. Therefore, its application should be economically justified.

Laser equipment

Recently, such a tool could only be used in industrial conditions. New technologies have made it possible to create enough mobile equipment.

How to saw aerated concrete blocks?

If complex forms are not supposed to be on the project of the built construction, then the purchase of an expensive power tool will be inappropriate. The most economical solution will be a hacksaw for cutting aerated concrete, used for work in a small volume.

The quality of the cut is affected by the strength of the block, technology, state/density of the material, humidity. In order for the cutting of aerated concrete to be even, you need a pencil and a square, with which you need to mark all four faces. Next, cuts 2-3 cm deep are performed along three faces (two long and one between them). How long the saw canvas will depend on whether you can get it to the end of the cut or not. The tool must be directed softly, without pressure, which prevents the saw leaving to the side. Also, aerated concrete blocks are often drank using the cub.

Electric disk saw

This tool copes with aerated concrete blocks quickly, but a lot of dust is formed during the saw process, protection for the eyes is necessary. At the same time, this tool is cheaper than a saber saw. From 2.5 thousand rubles.

  • It is better to lay gas concrete blocks on glue. For these purposes, it is worth using a proprietary cell that will provide you with a seam between blocks of 1.5-2 mm.

We select the kelm depending on the block used (375 or 365 mm wide). When using a wide gear spatula, the glue consumption increases, it turns out a thicker seam, and the masonry process is strongly delayed.

The thickness of the suture of the solution is too large when using a gear spatula

  • For cutting the stem in aerated concrete, it is advisable to use a grinder with a diamond disk for dry cutting. Then the strobes are quickly and easily removed with a gateway.

  • To accelerate the process of erecting a house as jumpers above door and window openings, as well as for armo-po-coat, it is easier to use ready-made U-blocks. But if you want to save, then such an element can be made independently from a whole block.

  • The speed of erecting a house directly depends on the quality of the masonry of the first row of aerated concrete. If it is laid perfectly evenly in level, then the masonry of subsequent rows is faster and easier.

To fit the first row, you can use a grinding machine

  • Do not put a laying of a row from two corners to meet each other. So it will be difficult to dress the rows and fit the last element in size.
  • To make laying the last block in a row, it is necessary to lay the last two gas blocks without glue, cut the last element taking into account the thickness of the seams. Then we put on the glue first a trimmed gas block, and then a whole element.
  • We do the dressing of blocks in the ranks. First we put the last gas block perpendicular to a row on another wall. Thus, he becomes the first in the next row. Then we measure the distance and saw off the element to the desired size. Then we perform the masonry using glue.
  • Gas block cutting options:

Plane

Clocking aerated concrete blocks try to give them an even surface, but it does not always work out. The rubble can cope with this task, which leverates the surface of aerated concrete and will make it perfectly smooth. The shirt consists of a wooden base with crashed small teeth, which are located at an inclination.

Chain electric saw

The use of chain electric saws for a gas concrete cut has advantages, but there are more minuses. Yes, it cuts quickly, helps to cut the U-configuration, convenient for cutting at an angle. But in the process of cutting, chain electric saws are quickly stupid, we need a chain with winning attacks, which costs noticeably more expensive than usual. In addition, the chain heats up in the process, the tool needs a break.

It turns out that in the use of chain electric saws it is more convenient for saber, but it becomes unusable faster, replacing the chain will lead to additional costs.

Hand saw

With small volumes of work, a hand hacksaw is used. With its help, they finish the openings of Windows and doors, also without it cannot be cope with when laying the initial tiers of walls. In order for the device that cuts the products to fulfill its function benignly, use auxiliary tools:

  • A metal corner, with which the correct angle of cut is controlled.
  • Ruler, marker or pencil, which are needed to determine the place of sawing.
  • Rubanok for gas concrete products, which equals the surface layer of masonry.

Aerated concrete is one of the hard materials, which means the choice of cutting tools should proceed from the quality of the cutting canvas. Drink with a hand hacksaw, which is designed for wood material, aerated concrete slabs incorrectly. It will take a lot of time and effort. The cutting element of the manual hacksaw should consist of carbide components with larger teeth. A hand saw is available with one handle and with two. The cost of the cutting tool is influenced by the distinguishing properties of the tool and the manufacturer.

Manual sawing

The widespread, but incorrect idea that the aerated concrete manually is a long and ungrateful, with poor results (uneven cuts, torn edges, tiring and unproductive).

But for an individual developer, it is possible and necessary to cut the blocks manually, since with a rather thick canvas the cut will always be even, and the porosity of the material does not make a large load on hand. It’s all about cutting technique, in the material and brand of foam block.

If you are going to cut a gas block or foam.Concrete brick of class B 2.0 and density (brand) D 400 with a hand sawing. But the class B 3.5 brand Block will make you think about the purchase of an electric cutting tool.

A properly selected manual saw allows you to make several thousand cuts, and it can be complex mowing trimmer line in the form of a trapezoid or hemisphere. The conclusion suggests itself: in addition to the foam block, it is important to develop the correct process of the process:

  • It is impossible to press on the saw much so that the canvas does not take to the sides. Aerated concrete should not be cut like boards or rails. The material is not cut, but crumbles, so the pressure here is not necessary in principle.
  • Before sawing aerated concrete blocks, make sure that they are well dried. Wet baby will get stuck in the sawdust and complicate the cutting process.
  • A smooth cut will turn out if the block is pre.Marked on three sides. Shallow cuts of 20-30 mm are made on markings.
  • The canvas should go through the cuts so that there are no deviations on the planes. The saw must be kept at an angle of 45 ° and not crushed on the canvas. So that the sawn piece at the end of the sawing does not fall and does not break off the uneven edges, the block should lie on the stand with his whole body.
  • The hacksaw should be long so that the canvas completely and with the margin overlaps the brick along the length.
  • To facilitate the work, you can make a tuzo from boards or plywood.
