白莲河抽水蓄能电站面板混凝土性能试验研究

Concrete Performance Testing Study for Face-slab of CFRD of Bailianhe Pumped Storage Power Station

在面板混凝土性能试验中,采用品质优良的高效减水剂、引气剂及I级粉煤灰,严格限制水胶比,适当增大粉煤灰掺量,优选出面板混凝土配合比,其单位用水量及水泥用量少,力学性能满足设计要求。

The high efficiency water-reducing agent,air-entraining agent and first-rate flyash are used in concrete performance test for faceslab of Bailianhe CFRD,meanwhile,striclty restricting water/binder ratio,appropriatly increasing flyash content,then,the optimal proportion of face-slab concrete with less unit water-content and unit cement-content is achieved,the mechanical properties meet the design requirement.
