干湿度条件下泡沫玻璃保温混凝土的收缩性能试验研究

摘要

利用废弃泡沫玻璃边角料制作泡沫玻璃保温混凝土，设计了3组不同配合比的泡沫玻璃保温混凝土在干湿条件下的收缩性能试验，对泡沫玻璃保温混凝土的干湿收缩发展规律进行了初步分析。试验结果表明泡沫玻璃保温混凝土在10 d之内的干燥收缩发展非常迅速，在10~60 d之间的干燥收缩增加比较缓慢，在60 d之后趋于稳定。%The foam glass insulation concrete was made using waste scrap foam glass ,designed the three groups of different mixture ratio of foam glass concrete shrinkage performance test under wet-dry conditions,analysised on the development regularity of foam glass insulation concrete.The test result showed that drying shrinkage of foam glass insulation concrete within 10 d development very quickly ,on the 10~60 d between the drying shrinkage increased slowly,tended to be stable after 60 d.
