摘要
研究结果表明,当粉煤灰掺量达到25%时,试样的力学性能最好;当激发剂掺量达到1.5%时,绝干抗折强度增加了36.5%,绝干抗压强度增加了27.6%;当有机硅防水剂掺量为0.4%时,2 h和24 h的吸水率分别为3.5%和4.2%,相比于空白试样,吸水率分别降低了88.3%和87%。
Influence of fly ash, activator and waterproofing agent on the properties of thermal insulation gypsum block is researched. The research results show that when the content of fly ash is up to 25%, the mechanical properties of samples is best; when the activator reaches 1.5%, dry bending strength increases 36.5%, dry compressive strength increases 27.6%;when the organosilicon waterproofing agent content is 0.4%, the water absorption rates for 2 h and 24 h respectively are 3.5%and 4.2%, comparing the gypsum sample, the water absorption rate reduces respectively 88.3%and 87%.
