摘要
通过粉煤灰胶砂试验,对硫酸钠、熟石灰、硅酸钠、石膏、硫酸钠熟石灰复合剂5种粉煤灰活性激发剂进行了试验对比研究,同时对低钙粉煤灰和高钙粉煤灰也进行了对比试验分析。对于大掺量粉煤灰构件来说,为了提高其早期强度,应选用高钙粉煤灰,活性激发剂宜选石膏或硫酸钠熟石灰复合剂。
By the experiments of fly ash mortar,the activating effect of five activators of fly ash （Na2SO4,Ca（OH）2,Na2SiO3,CaSO4,the mix- ture of Na2SO4 and Ca（OH）2） was compared and the impact of low-calcium fly ash and high-calcium fly ash on the mechanical properties of fly ash mortar was also analyzed.For a high volume fly ash part,in order to improve its early strength,high-calcium fly ash should be chosen and CaSO4 or the mixture of Na2SO4 and Ca（OH）2 should be selected as the activator.
