1.早期裂缝形成的内因1.1水泥混凝土堆聚结构的分层现象水泥混凝土在浇捣过程中,都会发生不同程度的分层现象,由于混凝土形成堆聚结构的过程中具有分层性,这种分层性使混凝土从表层到内层其强度越来越强,表层的抗拉能力最弱,这便是混凝土产生裂缝
1. The internal causes of early cracks 1.1 Stratification phenomenon of cement concrete aggregate structure In the pouring and pounding process of cement concrete, there will be different degrees of stratification, because of the formation of the polymer in the process of stacking structure with the stratification, this Stratification makes the concrete from the surface to the inner layer of its strength is more and more strong, the tensile strength of the surface layer is the weakest, which is the concrete cracks
