养护制度对活性粉未混凝土强度及微观结构影响的研究

Study on the effect of curing system on the strength and microstructure of reactive powder concrete

研究了标准养护、蒸汽养护和热水养护以及恒温温度和时间对RPC强度及微观结构影响规律,并初步探讨了标准养护和蒸汽养护对掺钢纤维RPC强度及微观结构影响。试验结果表明:100℃热水养护更有利于提高RPC强度,改善微观结构。

The effects on the strength and microstructure of RPC were studied of standard curing, streaming curing, hot water curing, the heating temperature and time.And the effects were studied on the strength and microstructure of RPC with steel fiber of standard curing and streaming curing.The results indicate that RPC under hot water with 100℃ is more favorable for its strength and microstrucure.
