摘要
介绍桐子林水电站主体工程混凝土配合比试验研究情况。根据混凝土设计指标,配合比设计采用掺加缓凝高效减水剂和Ⅱ级粉煤灰的"双掺"方案,并将混凝土设计龄期从28d延长至90d,提出了满足设计和施工要求的混凝土配合比,取得了较好的施工效果和经济效益。
This paper provides information on the test and study of the major works concrete mix of the Tongzilin hydropower project.The design of the concrete mix takes into account the use of two admixtures of set-retarding efficient water-reducing agent and grade II flyash according to the concrete design indexes,and the designed concrete age extends from 28dto 90d.The paper proposed the concrete mix that meets both design and construction requirements,thus achieving good results and economic benefits.
