高温地区薄壁墙体混凝土配合比研究与应用

Research and Application of Concrete Mix Ratio of Thin-Walled Wall in High Temperature Area

为研究高温地区大型供水项目工程中的水池薄壁墙体混凝土配合比,通过对砂子、水泥、骨料、水、外加剂等原材料进行试验分析,并对不同配合比的混凝土进行了坍落度和抗压强度试验分析,确定了最优配合比,从而提高了混凝土的和易性、抗渗性和耐久性,起到了降低水化热和提高混凝土强度的作用。

In order to study the concrete mix ratio of thin-walled wall of pool in a large water supply project in high temperature area during construciton, the raw materials such as sand, cement, aggregate, water, admixture and son on were tested and analyzed. The slumps and compressive strength of concrete with different mix ratios was experimentally analyzed to determine the optimal mix ratio, which improves the workability, impermeability and durability of concrete,and helps reducing hydration heat and improving concrete strength.
