Abstract
In this paper,the effects of different curing methods on mechanical properties and shrinkage properties of high performance concrete were systematically studied through compressive strength,flexural strength and drying shrinkage tests of concrete test blocks under natural cu-ring,standard curing and hot water curing.The experimental results show that the compressive strength of the concrete test block after natural curing,standard curing and hot water curing at 56 days is 141.46,155.04 and 161.56 MPa,respectively.Under the same conditions,the bending strength of hot water curing is the largest,followed by standard curing and natural curing.Under natural curing and standard curing,the bending strength at 56 d is 84%and 98%of the hot water curing strength,respectively.Compared with natural curing and standard cu-ring,the dry shrinkage of the test block under hot water curing at 14 days was reduced by 28.3%and 21.2%,and the dry shrinkage at 90 days was reduced by 26.6%and 17.6%,respectively.关键词
