摘　　要：研究了6种激发剂对粉煤灰吸附活性的激发作用以及激发机理.结果表明:Na2SiO3.9H2O的激发效果最好,当Na2SiO3.9H2O的用量为Ca(OH)2的1.5倍时,水合产物的活性增加了近一倍.激发剂激发粉煤灰活性的本质在于一方面增强了水合反应中对玻璃体的腐蚀作用,另一方面提高了水合作用的正向反应能力.We studied the excitation effect and excitation mechanism of six exciting agent on the activity of fly ash.The results showed that the Na2SiO3·9H2O was the best exciting agent,and the activity of hydration products nearly doubled when the weight of Na2SiO3·9H2O was 1.5 times of that of Ca（OH）2.The excitation mechanism of exciting agent was as follows： in hydration reaction the corrosion action on vitreous mineral was enhanced,on the other hand the forward reaction energy of hydration reaction was increased.
