摘　　要：在有工业废渣掺入的条件下,对石膏基泡沫混凝土的复合发泡剂进行了研究。探讨了单一品种发泡剂、二元复合发泡剂和三元复合发泡剂对新拌泡沫沉降高度、泌水量和消泡时间的影响。结果表明,在相同掺量条件下,三元复合发泡剂对降低泡沫沉降高度和泌水量、抑制泡沫消泡时间有潜在的协同效应。为新型泡沫混凝土的组成设计与应用提供参考。The foaming agent used in gypsum-based foam concrete with in present of industrial waste residue was studied. The effect of the single-doped foaming agent,co-doped foaming agent and ternary foaming agent on the settling height,bleeding volume and defoaming time of fresh foam were investigated. The results showed that ternary foaming agent had potential synergistic effects for reducing settling height and bleeding volume and retarding defoaming time of fresh foam in the same amount of conditions. It provides reference for composition design and application of new foamed concrete.
