The sulfate and chloride has great significant erosion on concrete structure. To provide theoretical reference for practical engineering application, this paper describes the mechanism and influencing factors of concrete sulfate and chloride erosion briefly, then discusses the main measures to improve the salt erosion resistance of concrete by combining the research status.

In this paper, the mechanical properties and durability of tuff stone powder concrete were systematically studied by comparing the performance of fly ash concrete under the same test conditions. The results showed that under the same age, the mechanical, shrinkage performance, sulfate corrosion resistance and early cracking performance of tuff stone powder concrete were same as fly ash concrete. The test results could provide sufficient technical support for the feasibility of tuff stone powder as concrete admixture.
