Quantification of the actual expansion and deposition of rust in reinforced concrete

The expansion of rust is often inhibited by the compression from concrete and the effects of the diffusion of rust, which obscure the actual amount of damage caused by the corrosion of the reinforcements. In this work, the relationship between the actual expansion and deposition of rust with a certain amount of corrosion is quantified by directly monitoring concrete displacement with digital image correlation (DIC) through accelerated corrosion...
