Experimental study on rehabilitation of concrete members by electrodeposition method

Abstract

Electrochemical techniques are increasingly popular as a means of rehabilitating deteriorated reinforced concrete. One such method is presented in this paper. The aim of electrodeposition in concrete rehabilitation method is to fill the cracks in concrete and to coat the concrete surface by electrodeposits of chemical compounds. The results indicate that electrodeposits formed on the concrete surface are able to close concrete cracks and to coat the concrete surface. In addition, the investigations show that the presence of electrodeposits led to a substantial decrease of concrete permeability and an improvement of the mechanical property of the cracked concrete beam. Therefore, it may be considered that the electrodeposition technique can be usefully applied as a rehabilitation method for cracked reinforced concrete structures.
