摘要
Abstract
The effect of 3％,6％and 9％silica fume on the properties of self-compacting high-strength concrete was studied by using large mineral admixtures to replace the cement.The results show that with the increase of silica fume content,the J-ring barrier expansion time decreases,the J-ring expansion degree increases first and then decreases,and the J-ring edge center height difference decreases.The optimal content of wollastonite with J-ring barrier expansion time is 9％.The content of wollastonite with optimal J-ring barrier expansion is 6％.The optimal content of wollastonite in J-ring barrier is 9％.关键词
