- Synopsis
- This paper focuses on the corrosion of reinforcement buried in concrete mixed with seawater, based on seawater-mixed concrete research trends. In particular, the paper explains the influence of the use of seawater for concrete mixing on the long-term durability of concrete based on test results and existing research data such as long-term exposure tests, and it summarizes the current state of knowledge with regard to corrosion suppression method and the use of reinforcing materials other than carbon steel for concrete mixed with seawater. While mixing concrete with seawater tends to carry a negative image, the authors hope that this paper will contribute to the proper use of such concrete based on academic and engineering judgment as research advances are made.
