Effect of conductive coating on the cathodic protection and prevention of steel reinforcement in concrete

Pending

In this study, different conductive coatings based on a micro-graphite and a mix with graphene were investigated for their effect on the cathodic protection and prevention of steel reinforcement in concrete. A simple method has been developed to quickly measure the conductivity of the coatings. A layer of micro-cement-based coating was covered on the black conductive coating for protection of the conductive coating as well as ethics of concrete surface. A pull-out test was carried out to evaluate the bonding strength between different coating layers and concrete. An accelerated test was carried out to evaluate the durability of conductive coatings as anode for the cathodic protection and prevention of steel reinforcement in concrete. The testing results will be presented and discussed with respect to the cathodic protection and prevention, mechanical bonding, ands the durability of coatings.
