Abstract
The reduced service life of concrete structures in coastal or de-icing salt conditions is commonly attributed to corrosion generated by chloride. Therefore, extensive research is being conducted to estimate the time taken for threshold chloride ions to reach the reinforcement and break the protective layer, initiating the corrosive process. This study conducted an experimental investigation on controlled concrete, concrete incorporating 50% GGBS, and concrete incorporating both 50% GGBS and 2% Icrete as the replacement of cementitious materials, with three different water-cement ratios (0.3, 0.4, and 0.5). The comparison was made based on their compressive strength, chloride ion concentration at different depths, chloride diffusion coefficient, and their service life. The results indicate that the concrete incorporating both GGBS and Icrete performed better than that of the controlled concrete and concrete incorporating GGBS only, in terms of higher compressive strength, reduced chloride ion penetration, reduced chloride ion diffusion coefficient, and higher service life
Keywords: Service life prediction, GGBS, Icrete, chloride ion concentration, diffusion coefficient
