摘要
近年来，预拌混凝土的应用越来越普遍。预拌混凝土坍落度的经时损失，往往造成现场混凝土泵送或成型困难。本文分析了预拌混凝土坍落度经时损失的机理，介绍了几种控制预拌混凝土坍落度经时损失的方法。
The ready-mixed contrete is widely used, and the gradualy loss in slump will cause some difficulty in concrete pump or placement. For as stated above, in this paper, the loss mechanism in slump of ready-mixed concrete is disscused,and some methods for controlling the loss are introduced.
