砂、石含水量对混凝土强度影响分析与控制

Analysis and Control of the Influence of the Water Content in Sand and Stone on Concrete Strength

通过案例分析,露天堆放的砂、石料,由于含水量不确定,必须在配制混凝土时,预先测出砂、石的含水率,调整施工配合比,以确保混凝土强度,保证工程质量及安全。

After case analysis, water content of the sand and stone stored in the air is found to be uncertain; so in concrete mixing, it has to pr-test the water content of sand and stone and to readjust the mix proportion to make sure the concrete strength and guarantee the engineering quality and safety.
