摘要
近年来,预拌混凝土在工程中的应用越来越普遍。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,探讨了几种控制预拌混凝土坍落度经时损失的方法。
The ready-mixed concrete is widely used in many projects in these years, and the gradually loss in slump will cause some difficulty in concrete pump or placement. In this paper, the loss mechanism in slump of ready-mixed concrete is discussed,and some methods for controlling the loss are introduced.
