界竹口电站夏季混凝土质量控制

Concrete quality control in summer at Jiezhukou hydropower station

界竹口水电站由于基础混凝土浇筑在高温季节施工,带来了混凝土的防裂质量问题。项目通过优化混凝土配合比、降低混凝土浇筑温度、混凝土表面保护、合理安排仓位和安排拆模时间及出现裂缝的处理措施等几方面入手,对混凝土质量进行控制。

Because the foundation concrete pouring was in summer, the high temperature caused the problem of crack control. By optimization of the concrete mix proportion, the lowering of concrete pouring temperature, proper storehouse arrangement and striking time as well as crack treatment measures, the concrete pouring quality was controlled.
