普通砼配合比设计中的几个要点

Several main points of mix proportion design of ordinary concrete

本文作者根据日常工作中对普通砼配合比设计试验数据的分析 ,对如何确定水灰比、砂率、用水量进行了讨论 ,并对如何确定砼 7天强度与 2 8天强度关系进行了总结。

WT5BZ]By the conclusion of the experiment data of the mix proportion design of ordinary concrete in the daily work,how to determine the water/cement ratio,sand ratio,water content is discussed in this paper.And how to determine the relationship between the 7d strength and the 28d strength is concluded.
