摘　　要：经对影响泡沫混凝土性能的主要因素的相关性分析发现,在不含速凝剂和激发剂的体系中,泡沫混凝土的流动性与其起泡性能、稳泡性能存在相关性。泡沫混凝土的凝结时间与泡沫混凝土的起泡性能、稳泡性能不存在相关性。泡沫混凝土的容重与强度有一定相关性。通过对泡沫混凝土的气泡结构进行分析表明在泡沫混凝土中加入适量的减水剂和甲基纤维素,有助于改善泡沫混凝土的气泡结构。By correlation analysis about the main factors that affect the properties of foamed concrete, we found that , in the system which ex- clude quick-setting agent and activator, flow ability of the foam concrete is related to the foamability and the foam stability. The setting time of con- crete is not correlated with the foamability and the foam stability. There is correlation to some extent between the density and strength of foamed con- crete. By observing the pore characteristics of several different ratio foam concrete with stereomicroscope, we found that adding water reducing agent and methyl cellulose to concrete can produce more small holes, and improve roundness of the pore.
