Crack closure and rehabilitation of chloride contaminated reinforced concrete structures

摘要

Apparatus to electrodeposit a chemical composition into cracks in concrete filling same is disclosed. The apparatus is comprised of a dam (reservoir) which is placed over the crack to be filled, an electrolyte which is received within the dam (reservoir), a direct current power source and an electrode which is received within the electrolyte and acts as an anode. The steel reinforcing rods within the concrete act as the cathode. Application of direct current from the power source to the electrode and the reinforcing rods causes the electrodeposition of a chemical composition into the crack filling same and the repassivation of the reinforcing rods within the concrete.
