The role of the cement block in the building is introduced

- Feb 25, 2018 -

Cement block is a commonly used material in the construction industry. The cement pad is usually made of block mechanism, which can fully guarantee the quality and strength of the cement block.

The cement block is usually used for building load bearing, which can guarantee the quality of the building, and it has certain protective effect on the reinforced concrete.

What else does the cement block do in the construction industry?

Let me introduce you.

1. The protective layer of the external force has the anchoring force of the steel bar, and the anchorage force between the concrete and the steel reinforcement is used, and the two are closely combined to participate in the work together.

When the protective layer is too thin or missing, it reduces its anchoring force and reduces the force and bending moment of the structure.

2, fire protection layer of concrete has a certain thermal insulation effect, can more easily to soften when you encounter fire reinforced protection, if too thin, protective layer thickness under the environment of high temperature easy craze, cause reinforced in overheating and reduce the strength to destroy the whole structure.

In 2003, a project in hengyang, hunan province, was caused by high temperature and high heat caused by fire.

3, easy maintenance structure durability of concrete protective layer is too thin in the infiltration of wet gas and water, too thick, easy to produce cracks, these could make the steel corrosion and inflation, so that the destruction of a concrete influence use and security of structure.

4. From the calculation formula of flexural capacity of the normal section, it can be seen that when the thickness of the reinforcement is too thick, the effective height of the cross section h0 is reduced, and the flexural capacity of the section is reduced.

It can be seen that the protective layer thickness is an important factor affecting the bearing capacity of the structure. In building materials, the application of cement block machine is very extensive.
