Abstract

Reinforced concrete systems are in many sectors of infrastructure. Due to a combination of elevated compressive strength from the cement and aggregates and tensile strength from the reinforcing steel, reinforced systems are favorable in construction applications where high strength is desired. However, while reinforced concrete is in service, it can be introduced to contaminants that cause corrosion. Contaminants can leach through the porous matrix of the concrete structure and influence initiation of corrosion products on reinforcement. Corrosion is the primary cause for advanced deterioration of concrete structures. Concrete deterioration has promoted research efforts for the protection of future systems. This research evaluates the suitability of corrosion resistance with the implementation of biochar and bentonite admixtures in concrete. Methods for determination of suitability include open circuit potential testing, force migration testing and strength testing on various admixture integrations. Each testing scenario ultimately indicates that the combination of biochar and bentonite negatively influences corrosion resistance and strength characteristics.
