摘　　要：对泡沫自身的容重、掺量、孔径分布等因素对泡沫混凝土性能的影响进行研究,结果表明:泡沫容重对泡沫混凝土的强度等性能有很大的影响,泡沫容重在70g/L～90g/L时最为合适;随着泡沫掺量的增加,泡沫混凝土的干表观密度及强度逐步降低;泡沫孔径分布不均匀,对泡沫混凝土的力学性能有负面影响。Properties of the foamed concrete influenced by weight of foams,Experiences indicate:the weight of foams have great influence to the strength of the foamed concrete,the best weight range of foam is 70-90g/l.As the increase of foam quantity,the density and strength reduce gradually.If the distribution of the bubble diameter is inhomogeneous,the strenth is lower in the same dry density.

关 键 词：泡沫混凝土 泡沫容重 泡沫掺量 泡沫孔径分布
