This paper reports on the assessment of physico-chemical properties of periwinkle shell ash as a replacement for cement in concrete. Physical properties like specific gravity, fineness, bulk density and moisture content of the periwinkle shell ash were determined and compared with the specification of American society of testing and material. The chemical composition of the ash was determined and compared with the specifications of American society of testing and material. Compressive strength of percentage replacement of cement with periwinkle shell ash of 0, 10, 20, 30 and 40% at 28 days of curing was also determined with mix ratio of 1:1:2 and 1:2:4. Periwinkle shell ash calcined at 800 and 1000 ˚C shows satisfactory result in terms of fineness, chemical composition and 28 days compressive strength activity index and could be used as partial replacement for cement in concrete preparation.
