摘　　要：研究了泡沫混凝土在填充轻质骨料、复合有机聚合物后的干燥收缩特性。结果表明,泡沫混凝土干燥收缩主要来源于毛细孔失水产生的收缩应力,填充体积稳定轻质骨料或复合憎水聚合物均有利于改善泡沫混凝土的干燥收缩性能。The dry shrinkage performances of foam concrete filled with lightweight aggregate and organic polymer are studied. The results show that the dry shrinkage of foam concrete is primarily from shrinkage stress due to evaporation of micro pore water. Filled with volume stabile lightweight aggregate or hydrophobic organic polymer will significantly improve the drying shrinkage performance of foam concrete.
