Durability analysis and assessment of existing concrete structures in coastal environment
By analyzing the microstructures,pore size distributions,and chloride profiles of concrete in four venues of Zhuhai Sports Center,the durability performance of existing concrete structures in coastal environments was studied and their durability levels were assessed.The results indicate that existing concrete structures in coastal environments have varying degrees of sulfate attack and chloride erosion problems.Concrete members located on outdoor windward and humid environments are more severely affected by sulfate attack and chloride erosion,and the proportion of large pores in concrete is relatively small;The corrosion problems faced by concrete members located on the outdoor leeward and indoor environments are relatively light,and the proportion of large pores in concrete is relatively large.Based on the durability analysis results of existing concrete structures in coastal environments,it is assessed that the durability of the concrete structures of the four venues in Zhuhai Sports Center does not meet the requirements and the durability treatment measures are provided.
