摘　　要：泡沫混凝土的抗压强度,已经成了其开发应用的瓶颈。通过对发泡剂原液的结构、泡沫结构以及发泡剂泡沫与水泥、粉煤灰浆料相互搅拌混合过程的分析,发现发泡剂本身的性质、最佳稀释倍数以及最合适的水灰比是决定泡沫混凝土抗压强度的重要因素。要提高发泡剂的性质,关键在于使用"多羧基单烃基"的表面活性剂和与之配套的稳定剂。Foam concrete pressure resistance has been one of the bottle-necks of development.Through analyzing original fluid composition, foam composition and the process of blending foam agent, cement and coal ash slurry material, it is discovered that the property of foam agent, op- timal dilution rate and optimal water cement ratio are crucial factors that establish good pressure resistance of foam concrete.The key factor of im- proving foam agent performance is to use ＂polycarboxylic monohydrocarbyl＂ surfactant and compatible stabilizer.
