养护方法对混凝土楼板裂缝的影响

Influence of Curing Methods on Cracks of Concrete Slab

通过试验研究和工程实例,指出减水剂的掺入大幅度地增加了混凝土的早期收缩,而早期养护能大幅度减小掺外加剂混凝土的早期收缩和后期收缩,对控制混凝土的非荷载裂缝十分有利。

Based on the experimental study and practical projects, authors introduce that the addition of water reducer will enormously increase the early-age shrinkage of concrete, and also present that the early-age curing will reduce the early-age shrinkage and the late shrinkage, which can well control non-loaded cracks.
