高石粉含量普通混凝土的坍落度损失问题及解决措施

The slump loss problem and solution of the ordinary concrete with high stone powder content

从外加剂复配和混凝土配合比设计的角度出发,提出了几种解决普通混凝土坍落度损失问题的方法,并分别进行试验验证,成功解决了某搅拌站高石粉含量普通混凝土的坍落度损失问题,在实际生产中取得了良好的应用效果。

From the concrete admixture compound and concrete mix design points,some solutions of the slump loss problem have been proposed in this paper. Through the test,the slump loss problem of the ordinary concrete with high stone powder content has been solved successfully in one mixing station. And good results have achieved in practical production.
