NON-DESTRUCTIVE METHOD TO EXAMINE PERFORMANCE OF CONCRETE IN SULFATE ENVIRONMENT

This paper describes a study carried out to examine the performance of various high performance concrete in sulfate environment,such as high performance concrete inside fly ash,and Portland cement concrete,and resist-sulfur cement concrete.They experienced dry-wet cycle in sodium sulfate solution.The parameters in the durability performance of concrete were loss ratio of weight and relative dynamic modulus of elasticity.They said that high performance concrete inside fly ash has better repellence to sulfate environment.
