摘要
研究了活化粉煤灰对水泥的凝结时间和胶砂强度的影响．实验结果及ＳＥＭ、ＤＴＡ、ＸＲＤ分析表明，活化粉煤灰比原状粉煤灰活性显著提高，可加速水泥早期水化，加快水泥浆体的凝结和硬化，是一种优质水泥混合材及促凝材料．
The effects of activated fly ash (AFA) on cement setting time and mortar strength are studied. Test results and SEM, DTA, XRD analyses indicate that the activity of AFA is obviously higher than that of fly ash (FA). AFA can accelerate cement early hydration, promote setting and hardening, and is an excellent cement admixture and setting accelerator.
