These may corrode and expand the reinforcement, damage the concrete and affect the use and structure.
The anchoring force between concrete and reinforcement is used to firmly combine them and play a role together.
1.
The protective layer has anchoring force to the reinforcement.
Kunming Xinteng trade product recommendation: Cement cushion block 2.
It can be seen that the thickness of the protective layer is an important factor affecting the bearing capacity of the structure.

The cement cushion block can bear external force.
Kunming Xinteng commercial products recommendation: Cement cushion block 4.
What are the specific functions of building cement cushion blocks? Next, Kunming Xinteng commerce and trade Xiaobian will take you to understand.
3.
Cement cushion blocks are widely used in construction sites.
When the protective layer is missing or too thin, the anchoring force decreases, and the role of the structure against axial force and bending moment also decreases.
The above is the knowledge sharing of the role of cement cushion block in building construction.
If the protective layer in the concrete for maintaining structural durability in the cement cushion block is too thin, it is easy to penetrate moisture and water; Too thick is prone to cracks.
If the protective layer is too thin, it is easy to crack under high temperature environment, resulting in overheating of reinforcement, reduction of strength, and damage to the overall structure.

How to do concrete insulation and curing in winter? Here, you can choose all kinds of industrial products..
The fire protection layer concrete in the cement cushion block has a certain thermal insulation effect, which can protect the reinforcement that is easy to soften in fire.
From the calculation formula of normal section bending bearing capacity, it can be seen that when the gluten protective layer of cement cushion block is too thick, resulting in the reduction of section effective height, the section bending bearing capacity decreases.
In a word, cement cushion can not only bear external force, but also have heat insulation effect, so it is widely used in engineering construction.
