For a country like Nigeria and indeed the third world countries at large, to be able to achieve a sustainable infrastructural development particularly in the area of housing in the nearest future, low cost building materials especially those readily available within each geo political areas must be exploited and used to make housing affordable for all and sundry. The inflationary trend in the Nigeria economy escalated the cost of building materials to the extent that many of the conventional building materials are no longer affordable for the construction of low cost housing. This research presents the study of the suitability of periwinkle shells as fine and coarse aggregate in construction works. Experimental and statistical approach was adopted in this project. Physical and mechanical properties of periwinkle shells and crushed granite were determined and compared. A total of sixty (60) concrete cubes of size 150 x 150 x 150 mm with different percentages by weight of crushed granite to periwinkle shells as fine and coarse aggregate in order of 0%, 10%, 30%, 50% and 100% inclusion of periwinkle shells were cast, tested and their physical and mechanical properties were determined. Compressive strength test showed that 30% replacement of granite by periwinkle shells and 30% replacement of sharp sand by periwinkle fine aggregate were satisfactory without compromise in compressive strength requirement for a mix ratio 1:2:4. Also, the cost analysis shows a 24% savings in cost when periwinkle shells are used holistically (100%) as coarse aggregate and 6.8% savings in cost when 30% are used to replace granite as coarse aggregate.
