This paper presents the results of an experimental investigation into the effects of exposure to wet and dry cycles on compressive strength and water permeability resistance in organic corrosion inhibitor concrete. Two types of organic corrosion inhibitors were investigated. One is added to the concrete mix (SKG.1), and the other is applied to the concrete surface (SKG.3). Wet-dry cycles were used, with two days wet and five days dry. Under the effect of three chloride concentrations at 3.5, 5, and 7% of NaCl solution, after 7, 28, 84, and 200 days of exposure, compressive strength and water permeability were determined. The results indicated that the concentration of NaCl solution had affected the compressive strength of concrete (C) under exposure to wet-dry cycles. SKG.1 has reduced the effect of chloride solution on both the compressive strength and water permeability of concrete exposed to wet and dry conditions. The influence of the NaCl solution on compressive strength appear to be minimal after exposure to wet and dry cycles in the sample (OS) where SKG.3 was applied on the concrete surface.
