摘要
自密实混凝土仅依靠自重就能够流动,在浇筑时不需要振捣,并能保持良好的匀质性,具有良好的工作性、力学性能与耐久性。针对自密实混凝土的特点和施工要求,通过试验研究与分析,详细论述了硅灰对自密实混凝土流变性、强度、耐久性、稳定性及触变性等性能的影响,并对其改善的机理进行了分析。
Self-Compacting Concrete（SCC） can flow without vibrating, only with deadweight and also can keep good homogenization, having good workability, dynamic characteristic and durability. Against the characteristic and construction requirements of SCC, via experiment research and analysis, belabored the effect of silica fume on rheological property, strength, durability, stability, thixotropic property of SCC, and the effect mechanism was analyzed as well.
