How To Cut Gas Silicate Blocks

Main process personalities

Depending on the specifics of the work, a variety of devices can be used: from extensively common options to special equipment.

In addition, the type of concrete that will be processed is of great importance. The aspects for which the tool is selected are as follows:

Advice! When determining this or that option, it is certainly worth considering whether there is an armature in the design, since it will disable ordinary cutting discs in an extremely short time.

Hand saw

Layout of aerated concrete walls.

The design of a saw, designed to cut aerated concrete, is extremely similar to an ordinary hacksaw for sawing wood. The canvas is made from the same in, but its thickness is significantly greater. This is done in order to avoid deformation when sawing hard c. The use of a hand saw is widely used for working with gas silicate blocks with small volumes.

She performs sawing of additional blocks: these works take place traditionally at the final laying of the wall or corner places.

How To Cut Gas Silicate Blocks

The best hand saws for gas silicate blocks use a carbide-tipped blade such as high-carbon steel.

Hand saws for aerated concrete are produced in 2 types. an ordinary hacksaw and with 2 handles.

Extreme is the most comfortable to use and significantly simplifies work.

The main differences between hand saws for working with gas silicate blocks are:

  • Blade length;
  • Steel thickness. the quality of the cut directly depends on it;
  • Soldering on the teeth (on each tooth or every other).

Reciprocating saw

Saw for aerated concrete.

Such a saw is not only effective in its own use, but the work and maintenance with it is quite simple.

Reciprocating electric saw is an electric hob that at first glance resembles the construction of a chain saw.

But it differs in that sawing is done with special flat blades (instead of a saw chain), in fact, similar to the blades of a bow saw.

In the process of work, the blades quickly move back and forth with an amplitude of 30-50 mm, creating an imitation of the movement of an ordinary hacksaw.

Basic properties of reciprocating saws:

Building a house from aerated concrete blocks.

    Number of moves per minute, frequency (2.5-3 thousand.

Strokes per minute);

  • Saw stroke length, amplitude (19-32 mm);
  • Cutting depth for certain.
  • Electric reciprocating saws are used at the workplace for sawing blocks, as well as for laying cable networks.

    Caring for such an inventory is simple: at times, using an oiler, you need to drip at least some machine oil into special lubricating holes located in the saw blade.

    Reciprocating electric shovel of this German plant from the outside is extremely identical with an ordinary chain saw.

    When cutting blocks, two canvases are used.

    A significant drawback is the relatively rapid wear of the iron parts of the saw.

    The main advantage is the safety and ease of use of this tool.


    The key disadvantage of the chain saw is the rapid wear of the cutting blade, since it is designed for wood processing, but it is not used for its intended purpose.

    To prevent such a problem, it is better to purchase a special chain with victorious soldering.

    It costs more than a regular chain, but lasts longer. You can find various models of such devices with different features and properties.

    During cutting, intense overheating and chain stretching are noticed. As a result, the master has to get rid of the 1st link in order to return the chain to its previous size. To prevent overheating, you should turn off the equipment just right.

    The electric engine is afraid of the action of dust, which accumulates as the gas silicate blocks are used intensively. As a result, the saw becomes unusable and cannot be repaired.

    How to saw with a hacksaw using a miter box

    To make the process of cutting gas silicate blocks convenient and efficient, you can use a special device called a miter box.

    It looks like a rectangular wood structure in the form of 2 letters P, connected by corners.

    A gap is placed between these elements, providing a cut. To strengthen it, you need to fix wood blocks on both sides. The dimensions of the gap are selected in such a way that the saw has a free run, but does not "walk". In the platform, the gap is slightly wider than in the side, as waste will accumulate there.

    To ensure a good degree of rigidity, it is better to choose huge corners made with a thick alloy. The block to be cut is placed inside the place from the letters "P", and a hacksaw is installed in the gap.

    Before starting the workflow, you need to do the following:

    • Use a pencil and ruler to mark up.
    • Then it is worth making shallow cuts along it.
    • After that, you can use the miter box: a block is placed in the work area, and later the necessary fragments with marks are cut off.
