The durability study of cement-based material in sulfate environment

This paper describes a study carried out to examine the performance of various high performance minute stone concrete,they are made up of compound admixtures,riddled sand,minute stone,portland cement concrete and resist-sulfur cement concrete.They experienced 100 dry-wet cycle in sodium sulfate solution.The parameters in the durability performance of concrete were variety ratio of weight,the flexural strength and the compressive strength.The results show that the concrete variety ratio of weight can reflect its durability in a certain extent.The flexural strength of concrete is more sensitive than the compressive strength and it can better reveal the destroy grade of the concrete.Besides,the paper offered the reference prescription to mix concrete in salt region.
