Abstract：Cracks in reinforced concrete were sealed by electrochemical deposition method(EDM).Three types of anode materials,Cu,Zn,Fe and their corresponding CuSO4,ZnSO4,Fe2(SO4)3 electrolytes were used in EDM.The effects of current density,electrolyte solution concentration,and electrodeposition time on crack surface closure rate,crack impermeability coefficient,ion diffusion depth in cracks,and electrode quality loss rate,were analyzed.The composition of the electrodeposited products was analyzed by X-ray diffraction and scanning electron microscopy.The results indicate that the degree of crystallization of electrodeposits is relatively high,and their shapes vary overall.Lower current density and lower electrolyte concentrations are most beneficial for the plugging effect of DEM on concrete cracks.
