摘要
合理的养护制度可保证高性能混凝土达到设计强度,但工程中因多方面原因,养护制度难以有效保证。以工程中常用养护制度为对象,试验研究了不同养护制度对高性能混凝土7 d、28 d和56 d抗压强度发展的影响,分析了不同养护制度的实质和作用机理。研究表明,湿草帘覆盖养护是综合效果最佳的养护方法,并以7 d养护为宜。试验结果可为工程养护制度的选取提供方案指导和量化支持。
The compressive strength of high performance concrete(HPC)can reach design strength by reasonable curing system.It is difficult to effectively ensure the curing system due to various reasons in engineering.Effects of different curing systems on the development of compressive strength of HPC at 7 d,28 d and 56 d were experimentally studied.The essence and mechanism of curing systems were analyzed.The results show that wet straw covering is the best curing method,and it is suitable to maintain for 7 d.The test results can provide scheme guidance and quantitative support for the selection of engineering curing system.
