摘要
大体积混凝土在固化过程中释放的水化热会产生较大的温度变化和收缩,由此产生的温度应力是导致混凝土出现裂缝的主要因素。通过对混凝土内部温度进行理论预测和现场监测,得到了大体积混凝土硬化期间温度及时间的典型曲线。
The heat of hydration,which is released during the course of solidification of the massive concrete,results in large temperature.Change and shrinkage.The temperature stress because of temperature change is a main factor of the concrete crack.by theoretical prediction and real site tests of the inner temperature of the concrete.The typical curves on development of temperature and time are obtained.
