Abstract:
A series of realkalization experiments were carried out on carbonated concrete members with stirrups. In these experiments, the locations and types of rebars were taken into consideration to evaluate the realkalization effects. Results show that during the realkalitation process, it makes no difference in realkalization effects whether the direct current is applied to rebar cage through longitudinal reinforcements or stirrups; realkalization process is the cooperation among electrolysis, electroosmosis and diffusion; excellent realkalization effects are achieved both in longitudinal reinforcements and stirrups no matter the location, dimension or types of rebar are embedded.
