Review of durability testing of reinforced concrete in marine environment

This paper presents a review of the characteristics and status of exposure tests in marine environment and indoor accelerated tests of reinforced concrete,and summarizes the durability testing methods at home and abroad.The authors point out that the development trend in this area is to study the durability of reinforced concrete in an unsaturated state and the coupling effect of load and marine environment.An important task is to explore the correlation between the exposure tests in a marine environment and the accelerated tests in an indoor simulative environment,and develop a damage deterioration and life prediction model for reinforced concrete.Thus the deterioration rules and the service life of the reinforced concrete in the marine environment can be predicted based on the results of the indoor accelerated tests.
