With the zinc salt and magnesium salt solutions, the influence of anion types on the electrodeposition healing effect of concrete cracks was investigated, four parameters such as rate of weight gain, surface coating, crack closure, and crack filling depth were measured, and the mineral composition and appearance of electrodeposits in the cracks were analyzed. The experimental results demonstrate that the electrodeposition healing effect is the best by adopting ZnSO4 and MgSO4 solutions. The mineral composition of electrodeposits in the cracks does not change with the anion types. The most particles of ZnO crystal appear as fusiform by using zinc salt solutions. If we selected MgSO4 solution, the Mg(OH)2 crystal was porous honeycomb. The electrodeposits present as flake structure while the other magnesium salt solutions were adopted.
