| ABSTRACT Corrosion of reinforced concrete structures is the one of the biggest problems faced by the construction industry, with billions of dollars spent annually on corrosion control strategies. Epoxy Coated Rebars (ECRs) have been reported to mitigate corrosion in Reinforced Concrete (RC) structures, but due to the inherent brittle nature of epoxy, its usage is limited. In this study we have proposed modified epoxy coatings on rebars using reduced graphene oxide (rGO) and graphene oxide (GO) along with carbon nanotubes (CNTs) and silane agents for improved ductility and corrosion inhibition properties. Hybrid mixture of CNTs and rGO/GO enhances the mechanical strength of the coating matrix whereas silane agents improve dispersion and bonding characteristics of nano fillers. Differently coated mild steel rebars with rGO/GO based coatings were subjected to accelerated impressed current corrosion. Performance of the coatings was evaluated by visual inspection, corrosion current, ultrasonic guided wave measurements, mass loss and residual tensile strength. Our results indicate that compared to rGO, GO in small proportion (0.4 wt% of epoxy resin) performs superior in corrosion inhibition. The GO/CNT nano composites could have potential application in the field of modified ECR reinforced concrete structures. Introduction Corrosion of civil infrastructures is the biggest challenge faced by the construction industry worldwide, and it is estimated that billions of dollars are spent for their repair and rehabilitation. About $2.5 trillion USD is the global cost of the corrosion related maintenance and repairs strategies in all industries [1,2]. Over $ 100 billion USD per annum worldwide are spent to repair and maintain concrete infrastructure alone [3]. Reinforced concrete (RC) is the most widely used material for construction in infrastructure industry which suffers corrosion related premature failures. Corrosion is a destructive electrochemical process that occurs between a metal and its environment [4]. The construction of concrete structures utilizes cement which is responsible for CO2 emissions leading to environmental pollution [5]. |
