摘　　要：以硫铝酸盐水泥为胶凝材料,复掺一定比例的粉煤灰和硅灰,以氯化铝和碳酸氢钠为发泡剂,采用化学发泡的方式制备新型硫铝酸盐水泥泡沫混凝土,并对泡沫混凝土的性能进行了研究。结果表明,该泡沫混凝土与已报道的硫铝酸盐水泥泡沫混凝土相比具有更高强度和更低的导热系数。A new type of sulphoaluminate cement foamed concrete was prepared by chemical foaming with sulphoaluminate cement,fly ash and silica fume as cementing materials and aluminum chloride and sodium bicarbonate as foaming agents. The performance of foamed concrete was studied and the results show that the foamed concrete has higher strength and lower thermal conductivity than the previously reported sulphoaluminate cement foamed concrete.
