公伯峡水电站面板混凝土配合比试验研究及应用

Study and application of the experiment in mix proportion of facing concrete desk of Gongboxia Hydropower Station

公伯峡水电站在施工前对面板混凝土配合比的各项性能指标进行了试验研究,试验采用掺加高效减水剂、新型减缩剂、优质粉煤灰等方案,提出了满足设计和施工要求的配合比,在实际应用中,取得了较好的施工效果和经济效益。

Gongboxia hydropower station researched on the each of performance indexes of facing concrete, the experiment gained the mix proportion that satisfied the requirements of design and construction by using the water reducer, the systole reducing and high quality fly ash etc. It acquired construction technique and economic benefit fairly in practice.
