浩口水电站大坝碾压混凝土配合比设计及原材料试验

Mix Proportion Design and Raw Material Test of RCC for Haokou Hydropower Station Dam

浩口水电站大坝为碾压混凝土重力坝,根据大坝碾压混凝土材料的设计要求,针对工程选择的原材料特性,进行混凝土配合比设计和性能试验.阐述混凝土配合比设计的步骤,指出混凝土配合比设计中应注意的问题,在此基础上提出满足设计要求经济合理的最佳碾压混凝土配合比.

The dam of Haokou hydropower station is a roller compacted concrete gravity dam.According to the design requirements of roller compacted concrete materials for the dam and the characteristics of raw materials selected for the project,the concrete mix design and performance test are carried out.This paper expounds the steps of concrete mix design,points out the problems that should be paid attention to in the design of concrete mix,and on this basis puts forward the best economic and reasonable roller compacted concrete mix to meet the design requirements.
