Embodiment 1
[0024] Using ZnSO 4 It is an electrodeposition solution with a concentration of 0.15mol / L, a pulse on / off time of 0.6ms / 0.8ms, and a current density of 0.5A / m on the concrete surface 2 , The electrode distance is 40mm. The electrodeposition solution was replaced every 7 days, and the test piece was taken out on the 21st day, and the crack healing rate reached 100%.
Embodiment 2
[0026] Using MgSO 4 It is an electrodeposition solution, the concentration is 0.1mol / L, the pulse on / off time is 0.8ms / 0.8ms, and the current density on the concrete surface is 0.5A / m 2 , The electrode distance is 40mm. The electrodeposition solution was replaced every 7 days, and the test piece was taken out on the 21st day, and the crack healing rate reached 96%.
