以脱硫石膏为主要胶凝材料,以粉煤灰为填料,通过掺加复合激发剂激发脱硫石膏-粉煤灰胶结材的活性,达到改善石膏砌块性能的目的;通过掺加蜡-醇复合防水剂,提高石膏砌块的耐水性能。试验结果表明,当粉煤灰填充量为脱硫石膏质量的20%时,对石膏强度影响最小;当复合激发剂B掺量为1.75%时,脱硫石膏-粉煤灰胶结材的活性得到最大激发程度;当蜡-醇复合防水剂掺量为0.4%时,新型脱硫石膏砌块的耐水性能达到最佳状态。
Using gypsum as the main binder and fly ash as the filler, the activity of the gypsum-fly ash cementitious material is stimulated by adding compound activator to improve the performance of the gypsum block; by adding the wax-alcohol complex Waterproofing agent, improve water resistance of gypsum block. The results show that when the amount of fly ash is 20% of gypsum, it has the least effect on gypsum strength. When the content of B is 1.75%, the activity of gypsum-fly ash cements is maximally excited Degree; When the amount of wax - alcohol composite waterproofing agent is 0.4%, the water resistance of the new type gypsum gypsum to achieve the best.
