The potential of periwinkle shell as coarse aggregate for concrete was studied in this paper. The properties of concrete made with periwinkle shell as coarse aggregate were examined. Test conducted on the concrete was compressive strength test. Prescribed mix designs of 1:1:2, 1:2:3, 1:4:6, 1:2:4 and 1:3:5 were used to produce concrete cubes used for testing.

investigation of the suitability of using periwinkle shell as coarse aggregate for making concrete in such coastal communities. Periwinkle shell is an agricultural waste material commonly found in coastal communities. They are relatively non-degradable, and, as such, constitute a great deal of environmental problems. Many of these

The bulk density of the periwinkle shells and river gravel was 515 kg/m 3 and 1611 kg/m 3 respectively. The low bulk density of periwinkle shells suggests that lighter concrete can be produced from them. The aggregate crushing value (ACV) was 59.6% and 27.1% for periwinkle shells and river gravel respectively.

The periwinkle shells used for this study were obtained from heaps at Okrika waterside, by Hospital Road, Port Harcourt, Rivers State, Nigeria. The length varied from 31.8mm to 63.96mm and diameter of about 16.9mm near one end and tapering to a point at the other end. The periwinkle shell aggregates were thoroughly washed

The use of the periwinkle shell in the production of lightweight concrete has been studied and accepted to be used for concrete works. Hard water containing detergent-like chemicals has been observed to be used in mixing locally produced concrete. This exploratory study is on the effect of water mixed with detergent in a concrete prepared with the periwinkle shell as a coarse
