Corrosion Damage and Life Prediction of Concrete Structure in a 41-Year-Old Steelworks.

ABSTRACT: Iron and steel industry emits a large amount of CO₂ and SO₂ in the process of steelmaking, and these acid gases lead to the serious corrosion damage of concrete structures. In this paper, the environmental characteristics and corrosion degree of concrete in a 41-year-old steelworks were investigated, and the neutralization life prediction of the concrete structure was carried out. The results showed that the temperature, relative humidity, CO₂ concentration, and SO₂ concentration in the steelworks were 1.32, 0.62, 1.28, and 13.93 times higher than those of the general atmospheric environment, respectively. These environmental characteristics in various sections were significantly different. The appearance change of concrete in the ingot casting b
