摘要
在本实验中,研究了粉煤灰的细度对水化特性和强度的影响.通过风力分级把两种粉煤灰组成一个粒度分布系列,同时,为了对比,还采用了其它混合材料,石英粉、硅灰进行了实验.
Abstract In a test series, the effect of fly ash fineness on hydration characteristics and strength was investigated. Two fly ashes combined to series of particle size distribution by means of air classification. In order that comparison with other additions, a guartz powder and a silica fume were tested.The results show that effect of fly ash finenesson pozzclanic reaction and strength is singnti-cant, even in the first 28 days. It is necessary that greathy increased fineness for improvement. At higher curing temperature pozzclanic reaction is dramatically accelerated.
