Why you can't build a house from hollow bricks

Hollow brick is a popular building material. It has become in demand due to the fact that it has light weight, cheaper than solid brick.

It is characterized by the presence of holes (vertical, horizontal, through or closed on one side). Voids can reach up to 45%.

Such a brick costs less, which attracts builders. Price for single ceramic brick M100 - 12 rubles. apiece (at Leroy). Solid building brick - price 15 rubles. apiece in the same store.

Why can't you build a house out of such a brick? Let's figure it out.

This material is also called perforated, slotted. It is made from various raw materials (cement, clay).

Hollow bricks are not suitable for heavy-duty structures, basements, foundations, ovens and plinths.

The material differs in the material of manufacture. At the construction site, 3 types are more common: white silicate, ceramic, hyper-pressed.

Working with such material is pretty quick. Brick channels allow the use of vertical reinforcement. It is convenient to make of brick

partitions. There is no heavy load on the supporting structures due to the holes. Some are used for low-rise buildings.

Hollow bricks are used to make gazebos, fences, verandas, outbuildings.

The hollow material has excellent sound insulation properties. Able to protect from outside noise. The brick is resistant to cracking due to the presence of air inside.

The main disadvantage hollow material - low strength. At sub-zero temperatures, the water that gets inside the hollow brick freezes and subsequently leads to deformation of the material.

When laying, it is required to make a thicker solution so that it does not flow into the holes.

The material has a high thermal conductivity, but without additional insulation it retains heat worse.

Conclusion: if the structure implies that it is required to use a lightweight brick, then a hollow version is suitable. But in any case, if the strength of the building is important to you, choose a solid material. The decision is always yours.
