Description
Technical field
A kind of concrete placingJi Shu of the present invention field, and in particular to anti-crack and anti-seepage coagulation based on cement-base composite material
Native pouring procedure.
Background technique
Concrete is applied in almost all of modern architecture as presently the most important one of construction material.But
Be, due to concrete (especially mass concrete and high-strength concrete etc.) generally existing shrinkage phenomenon, cause concrete cracking,
The reduced performances such as intensity, antiseepage, anticorrosive use swelling agent as bright existing for expansive concrete material currently on the market
Aobvious defect is phenomena such as heat of hydration of concrete is high, and concrete shrinkage deformation is big, generally existing concrete cracking, leakage, together
When, also greatly reduce concrete strength.
With the continuous development of component materials of concrete, people are not limited solely to pressure resistance to the performance requirement of concrete
Degree, but on the basis of basing oneself upon intensity, more focus on durability, deformation performance, the infiltration energy, corrosion resistance of concrete
Etc. overall target balance and coordination.The requirement of concrete performance indexes is than more clear in the past, refinement and specifically.Together
When, the promotion of Architectural Equipment level, novel construction process continuing to bring out and promoting, and concreting technology is made to need to adapt to not
Same design, construction and requirement.
Summary of the invention
