The problem of cracks, which is caused in structures by deforming effect, such as hydration heat, shrinkage, temperature difference of atmosphere, is very important and complicated.
由于变形作用(水化热、收缩、气温差)引起工程结构的裂缝是很复杂并很重要的问题。

The early cracking of concrete is usually caused by dry shrinkage, autogenous shrinkage of cement hydration and thermal-strain by hydration heat of cement.
