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.
混凝土的早期开裂主要是由于混凝土失水所产生的干燥收缩、水泥水化所产生的混凝土自收缩以及水泥水化热所产生的温度应变所引起。
The chemical shrinkage caused by cement hydration may bring out the volume change of mortar and concrete, and the appearance of cracking.
水泥水化反应引起的化学收缩会引起砂浆及混凝土的体积变化,可能会导致收缩裂缝的产生。
