Abstract: This study investigates the water permeability and sorptivity characteristics of periwinkle shell blended concrete under interrupted and uninterrupted curing conditions. The periwinkle shell ash was mixed in concrete at various percentages replacement of 0 %( control), 10%, 20%, 30% and 40% by weight of cement. Concrete beams, cubes and cylindrical samples were produced using the partial replacement levels and cured for 7, 28, 56 and 90 days under interrupted and uninterrupted conditions. The water permeability and sorptivity of periwinkle shell ash shows lower values at 10% replacement of PSA by weight of cement in concrete. The study concludes that blended concrete with 10% PSA was the optimum replacement level by weight of cement in concrete to produce durable concrete structures under interrupted and uninterrupted conditions.
