Experiment on Chloride Ion Content of Concrete Structure in Coastal Salt-fog Area

This paper chose the south-east coastal salt-fog area Shantou to carry out the experiment study on chloride ion content of concrete structure, through the chloride ion content field test on reinforced concrete structure in Shantou, respectively for the slat-fog atmosphere zone and the splash zone in marine environment, discuss the corrosion by chloride ion of long-time existing concrete structure.And then measure the chloride ion content of concrete cover in different depth, and determine the chloride ion diffusion model in different conditions concrete through comparative analysis.The result of study, can be used in directing the selection of design scheme for building in planning, and also it will help predict the corrosion time of reinforcement inside the concrete on different positions for existing structure.
