自密实钢纤维超高强混凝土试验
Experiments on the Self-compacting Steel Fiber Reinforced UHPC
摘要
Abstract
The effects of the ratios of water to binder (w/c), superplasticizer contents, steel fiber contents and the addition of silica fume and superfine slag powder on the fluidity, compressive strength and flexural strength of UHPC were investigated. The experimental results indicate that the w/c, superplasticizer contents and steel fiber contents have significant influence on the fluidity and strength. A type of UHPC with compressive and flexural strength of over 120 MPa and 20 MPa can be obtained by adding 2% superplasticizer, 2. 5% steel fiber, 4%~6% silica fume and 10%~15%superfine slag powder.关键词
