Evaluation of Rapid Chloride Permeability Test on Concrete Containing Steel, E-Waste Copper Wire and E-Glass Fibres

TLDR: In this article, the rapid chloride permeability test (RCPT) as per ASTM C1202 is presented to determine the chloride profile, concrete chloride resistivity and rate of corrosion.

Abstract: The main cause of reinforced concrete deterioration is chloride attack. Chloride ions penetrated into the concrete can destroy the passive layer around steel reinforcement provided by the high alkalinity and low pH of cement paste, activating electrochemical corrosion. Durable concrete gives more corrosion resistance of embedded steel that continuously ensures a stronger long life of the reinforced concrete structure. The concrete structures within the seashore areas allow chloride ions to easily penetrate into the concrete and reduce the life span of the structure. In this paper, the rapid chloride permeability test (RCPT) as per ASTM C1202 is presented to determine the chloride profile, concrete chloride resistivity and rate of corrosion. The specimens were prepared with concrete incorporating three different type fibres including steel, E-waste copper wire and E-glass fibres of 1.0% by volume of concrete. The RCPT was conducted for time period of 28 days, 56 days and 90 days. The final RCPT results of fibre-reinforced concrete mix with control mix concrete were compared. The test result shows that the E-glass fibre-reinforced concrete was more durable than the other concrete mixes.
