摘要
自密实混凝土是一种具有高工作性能的高性能混凝土。本文探讨了自密实混凝土工作性能的评定方法,并对掺加磨细矿渣的自密实混凝土进行了研究。通过分析磨细矿渣含量、胶凝材料总量、砂率、减水剂掺量对自密实混凝土流动性和强度的影响,配制了高工作性能和力学性能的自密实混凝土,为掺加磨细矿渣的高强自密实混凝土配合比设计提供了依据。
Self-compacting concrete （SCC） is a kind of high-performance concrete with high workability. This paper introduces the evaluation methods of workability, and studie the properties of the self-compacting concrete with the addition of ground granulated blast-furnace slag（GGBS）. After selecting the parameters of mix proportions, such as content of GGBS, sand ratio, and content of superplasticizer, components of high strength SCC with good workability, high mechanical properties is suggested. The experimental results offer references to mix proportion design of high-strength self-compacting concrete with GGBS.
