摘　　要：通过试验观测,分析不同养护条件下商品混凝土早期收缩裂缝发生和发展规律．文中指出提高混凝土早期强度和及早养护,可减小混凝土内部应力(包括收缩应力和温度应力)．加强早期养护既可提高混凝土初始强度,又可减小混凝土内部应力,是减少混凝土裂缝的有效手段．Based on the experiment observation, The crack occurrence and its development at early stage under different curing conditions are analyzed. It is pointed out that the increase of concrete strength at early stage and early curing can reduce the internal stress including both the shrinkage and temperature stresses. The reinforcement of the curing at early stage can increase the initial strength of concrete, and decrease the internal stress of concrete as well, so is the effective measure to prevent concrete crack.

关 键 词：商品混凝土 早期养护 收缩 裂缝
