摘要
采用新型增密硅灰与原装硅灰配制C70高强混凝土,通过对混凝土坍落度经时损失率、凝结时间、抗压强度、抗渗性的试验对比,发现新型增密硅灰对新拌混凝土坍落度经时损失率有减小趋势,对凝结时间有一定的缩短趋势,抗压强度、抗渗性基本一致。
Densified and original silica fume were adopted to prepare high-strength concrete of C70 respectively.Slump loss,setting time,compressive strength and impermeability of concrete were researched comparatively.The results revealed that densified silica fume decreased concrete slump loss and setting time.The compressive strength and impermeability of concrete with densified and original silica fume were in accordance.
