摘要
选取2种超细矿粉,采用正交试验方法,制备工作性良好的高性能混凝土,研究了超细矿粉代替硅灰对高性能混凝土强度的影响.结果表明:用超细矿粉替代硅灰配制的高性能混凝土强度得到明显提高,某些配比的试验效果优于硅灰,是硅灰优良的替代品.
This research replace silica fume of two kinds of ultra-fine slag. High-performance concrete with good workability are prepared by means of orthogonal design method to research the influenece on the strength. The result shows that the strength of high-performance concrete, which adds ultra-fine slag instead of silica fume, is enhanced greatly, and it is better than silica fume. Therefore,it is a good substitute of silica fume.
