摘　　要：以普通硅酸盐水泥为基材,用超细矿物外加剂和粉煤灰分别取代部分水泥,对比研究超细矿物外加剂和粉煤灰对泡沫混凝土抗压强度、吸水率、密度和浆体工作性的影响。结果表明:超细矿物外加剂在一定掺量范围内可降低泡沫混凝土的密度,降低吸水率,同时保证后期抗压强度。Taking the ordinary portland cement as the base material,and partial replacement of cement with superfine mineral admixture or fly ash,the different influence of superfine mineral admixture and fly ash on the compressive strength,water absorption,density and workability of foam concrete were compared and anlyzed. The results show that in a certain dosage range,the superfine mineral admixture can reduce foam concrete density,and reduce the water absorption rate,while ensure the late compressive strength.
