A STUDY ON REPAIRING INTERNAL DEFECTS INSIDE CONCRETE USING THE ELECTROCHEMICAL DEPOSITION METHOD

Abstract

In this paper, the feasibility of repairing internal defects inside concrete using the electrochemical deposition method is investigated. Various amounts of the air entrance agent (AEA) were added into fresh concrete to produce small air bubbles. Zinc sulfate was used as the electrolyte for the electrochemical deposition method. The dry unit-weight test, compressive strength test, splitting tensile strength test, four-probe electric resistivity, water absorption percentage test, open circuit potential test, scanning electronic microscope (SEM) and X-ray diffraction are carried out to investigate the repair results. Results show that the electrochemical deposition method is a promising rehabilitation method when internal defects are required to be repaired.
