摘　　要：以H_2O_2为发泡剂,以建筑垃圾、矿渣等为原料制备地聚合物基泡沫混凝土。考察建筑垃圾/矿渣质量比、碱激发剂用量、H_2O_2用量等因素对泡沫混凝土干密度、抗压强度和导热系数等性能的影响。结果表明,当建筑垃圾和矿渣质量比为5:7,碱激发剂用量为15%,H_2O_2用量为5%时,泡沫混凝土的综合性能最佳,干密度为298 kg/m^3,抗压强度为1.26 MPa,导热系数为0.075 W/(m·K)。Using H2O2 as foam agent,geopolymer-based foamed concrete were prepared with construction waste and slag as starting materials. The experimental parameters,which affected the dry apparent density,compressive strength and thermal conductivity of foamed concrete were discussed,such as construction waste /slag weight ratio,alkali activator contents and H202 contents. The foamed concrete exhibits the best properties with dry apparent density of 298 kg/m^3, compressive strength of 1.26 MPa and thermal conductivity of 0.075 W/（m·K） when construction waste to slag weight ratio is 5：7,alkali activator content is 15%,and H2O2 content is 5%.
