摘　　要：为解决泡沫混凝土浇注入烧结空心砌块后出现的塌陷问题,研究了几种稳泡剂和速凝剂对泡沫混凝土性能的影响。实验结果表明:羟丙基甲基纤维素醚掺量为0.05%时,泡沫混凝土的体积稳定性有所提高;ZJK铝酸盐速凝剂掺量为10%时,泡沫混凝土可脱模时间在30 min内。通过改进泡沫混凝土配合比解决了塌陷问题。To solve the subsidence problem of foam concrete filled into fired hollow blocks,the effect of foam stabilizers and accelerator additives on the property of fotma concrete were studied. The results of experiment show：volume stability of foam concrete was improved by adding 0.05%HPMC,the setting time of foam concrete was controlled in 30 mins by adding 10% self-made aluminate accelerating additive. The subsidence problem of foam concrete was solved through adjusting its formulation.
