摘要
本文研究了集料体积率和胶粉掺量对硬化砂浆干缩变形的影响,以及两者的复合作用。研究结果表明,改善集料的级配,提高集料含量,有助于提高硬化砂浆的抗裂性能。增加胶粉掺量也有利于改善硬化砂浆的抗裂性能。
This paper studies the influences of thevolumerate of cement paste and the content of polymer on shrinkage of the hardened mortar, and their combined actions. The results indicate that theenhaneing of the grade of aggregate and the vohume rate of aggregate is helpfill to the enhancement of its crack resistance. The increase of Ihe content of polymer is to be advantage to the hardened mortar＇s crack resistance too.
