Study on performance of inner curing high strength concrete
WANG Yizhe
Abstract：Under the condition of no standard curing,the method for mixing ceramsite as internal curing agent to C80 con-crete can achieve the purpose of self curing of C80 concrete. The effects of different amount of internal curing agent on the strength,drying shrinkage,sulfate attack resistance and pore structure of C80 concrete were studied,and the influence mechanism was also studied. The results show that the internal curing agent can improve the strength of concrete,reduce the drying shrinkage, improve the sulfate resistance,and minify the hole in concrete. When the amount of ceramsite reached 10% of the volume of fine aggregate,the best internal curing effect can be obtained.
