Abstract | Corrosion-caused cover cracking can lead to the serious deterioration of reinforced concrete (RC) structures. However, only a few experimental studies in the literature have examined the entire cracking process of specimens with a realistic configuration that consists of both the concrete cover and concrete core. Herein, the mechanism and process of cover cracking are experimentally investigated for cover and core specimens by using accelerated corrosion tests together with digital image correlation. The entire process of corrosion-caused cover cracking is experimentally recorded. The phenomenon of the rotation of the cover is first observed. Furthermore, the direction of the crack propagation, crack opening displacement (COD) profiles and the concrete expansion at the steel/concrete interface are measured. The relationship between total rust and the rust that causes expansion pressure on the surrounding concrete is examined. The test results are then used to validate a previously proposed elastic-body-rotation model for simulating cover cracking. |
