英文摘要	This paper describes a study carried out to examine the performance of various concrete in sulfate environment, such as concrete inside fly ash, and Portland cement concrete, and sulfate resistant Portland cement concrete. They experienced dry-wet cycles in sodium sulfate solutions. The parameters in the durability performance of concrete were loss ratio of weight and relative dynamic elastic moduli. They said that concrete inside fly ash has better repellence to sulfate environment. By analyzing the SEM of concrete and photo of sample show that fly ash can happen the second hydratation to disadvantage component Ca(OH)2 inside concrete, and build advantaged C-S-H gel to reform the microstructure of concrete effectively.
