摘　　要：为提高泡沫混凝土的抗裂性能,对不同水胶比、不同纤维和轻骨料掺量、不同干密度等级的泡沫混凝土材料进行了收缩试验,分析了影响泡沫混凝土收缩的主要因素.研究结果表明:在满足施工性能的基础上减少水胶比、添加纤维和轻骨料对减少泡沫混凝土收缩效果明显.For porpose of improving the crack resistance of the foamed concrete, the tests on the shrinkage of the foamed concrete with different water and cement ration, different fiber and lightweight aggregate percentage and different density, were conducted to analyze the factors. The results indicate that it is effective to reduce foamed concrete shrinkage by decreasing the water cement ratio and increasing fiber and lightweight aggregation on the premise that construction is not affected.
