Abstract:
The phenomenon of steel corrosion and concrete crack patterns under different water-to-cement ratios and cover depths of concrete was investigated. The steel corrosion of single reinforced concrete beam with different admixtures under repeated loading was also studied. It is possible to predict the crack patterns and mechanical behavior of concrete when steel corrosion is induced. The addition of inhibitors reduced the corrosion rate. If concrete undergoes repeated loadings, the resulting cracks will allow harmful elements in tidal zones to penetrate into the concrete. This will accelerate the corrosion rate, especially at high loading conditions.
