摘　　要：以石灰、石膏作为粉煤灰活性激发剂,用废弃聚苯乙烯颗粒（EPS）作为保温成分,通过优化配比,研制新型节能环保墙体砌块材料,分析了砌块材料的水化机理。XRD（X射线衍射）、TGA-DTA（热重-差热分析）和SEM（扫描电子显微镜）分析证实：当粉煤灰掺量为20%-25%、EPS为2.5%时,保温砌块材料的施工及保温性良好,耐久与耐候性能优良。A new kind of energy saving and environment friendly wall block material was prepared employing fly ash activated by lime and gypsum and waste polystyrene（EPS） grains as the insulating constituent.The ingredient ratio of each component was optimized and the hydration mechanisms of this new kind of wall block material was studied.The XRD,SEM and TGA-DTA results show that when the dosage of fly ash is 20%～25% and that of modified EPS is 2.5%,the heat insulation block material gets good construction property,heat insulation property as well as good durability and weatherability properties.
