ABSTRACT
Reinforcement corrosion in concrete is a major durability problem. A prime cause for corrosion initiation is due to the ingress of chlorides, derived either from the use of de-icing salts or exposure to marine environments (Bentur et al. 1997). Chloride induced corrosion leads to the reduction in reinforcement cross sectional area via formation of corrosion products. The increased volume of corrosion products results in tensile cracking and leads to structural failure. Electrochemical chloride extraction (ECE) is commonly used re-habilitation technique for corroded reinforced concrete. This study examined the impact of driving nanoscale pozzolans to the reinforcement while chlorides were being extracted.
