Article Preview

During the electrochemical realkalisation treatment for carbonated concrete, the bond strength between rebar and concrete was changed duo to the physical and chemical action. The pull-out test was used to study the effect of current density on the bond strength between rebar and concrete. The realkalisated products of the concrete were studied using X-ray diffraction (XRD). Test results show that after electrochemical realkalisation treatment (ERT), the bond strength of reinforced concrete increases; The current density has the significant effect on the bond strength; The amount of sodium silicate of the concrete is changed after ERT, Due to the increment of the sodium silicate that can increase the bond strength between the concrete and the rebar, it makes for the increase of the bond strength.
