| Abstract: | 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. |
