混凝土中使用机制砂的配合比设计方法

摘要

machine-made sand in the concrete problems that exist in the actual production process, the common concrete mix proportion "overall calculation method"design concept, by adjusting paste-aggregate ratio in concrete, and through the test to determine the optimal mixing proportion of concrete used in the machine-made sand, further settlement mechanism sand in concrete application in the process of poor liquidity, the problem of high sand ratio.%机制砂在混凝土实际生产过程中存在的诸多问题，采用普通混凝土配合比“全计算法”设计理念，通过调整混凝土中的浆骨比，并通过试验确定了混凝土中使用机制砂的最佳配合比，进一步解决机制砂在混凝土应用过程中流动性差、砂率较高等问题。
