摘要
在高性能混凝土生产中,通过使用膨胀剂改善混凝土的收缩性能较为普遍,从影响膨胀剂使用性能的因素着手,通过对不同水灰比或不同粉煤灰掺量的混凝土试件,在0、20、60、80℃等温度段和水养、标养条件下,对高性能混凝土限制膨胀率的影响进了试验研究,并通过试验,分析了膨胀剂在高性能混凝土中的使用效用。
It is normal to use the expanding agent to improve the shrinkage of concrete in the production of high performance concrete.The concrete samples with different ratio of water /cement and various quantities of fly ash blend were tested under0,20,60,80℃.and water curing,standard curing condition.Also,the control of expansion rate was tested.The efficiency of expanding agent in the high performance concrete was analyzed.
