大体积混凝土施工完成后，由于混凝土内水泥水化反应后产生大量的水化热，使得混凝土内部发生巨大的温差变化，温差变化容易导致混凝土中产生裂缝，对混凝土的强度和耐久性造成一定影响。通常可以采用改变混凝土配合比、使用大粒径石子和粗中砂、对混凝土进行保温、控制出机温度和浇筑温度、二次振捣、二次抹平、后台监测等方法进行控制，以减少混凝土内部裂缝的出现。

Large volume concrete construction is completed,due to the cement in concrete hydration reaction to produce a lot of hydration heat,the existence of hydration heat makes the concrete internal temperature changes,leading to the cracks of concrete internal,cause certain influence to the strength and durability of concrete. Usually can use change of concrete,the use of large particle size of gravel and coarse medium sand,for thermal insulation of concrete, the control of temperature and pouring temperature, second vibrating,secondary smoothing method,the background monitoring methods to decrease the cracking of concrete internal.
