龙滩水电站碾压混凝土技术指标与配合比设计

Technical Indexes and Mix Proportion Design of the RCC for Longtan Hydropower Station

对龙滩大坝碾压混凝土技术指标和配合比优化设计进行了综合分析与评述,并就龙滩工程提出的强度等级双龄期控制、原位抗剪指标、变态混凝土极限拉伸值等要求进行了探讨,从这几个方面提出实践过程中认识到的问题,与同行商榷。

This paper analyzes the optimal design of technical index and mix proportion of RCC for Longtan Dam and discusses the strength classification dual-age control, original position shear index and ultimate tensile of distorted concrete. Proposed several points to be discussed with the experts in the same filed.
