Abstract

The unabated increase in the cost Ordinary Portland Cement, OPC, has been one of the major factors militating against the provision of adequate and affordable housing in Nigeria and most African countries. Hence, this study investigated the possibility of using fowl egg ash (FESA) as partial replacement for Ordinary Portland Cement (O.P.C) in the production of concrete. Fresh concrete of mix ratio 1:2:4, blended with graded levels of fowl egg ash: (0%; 5%; 10%; 15% ,20%,25% and 30%) , using water-cement ratio of 0.5, were prepared to cast a total of eighty-four (84) concrete cubes of size 150mm×150mm×150mm and cured in water bath for 7ays; 14days; 21days and 28days respectively. The resulting FESA blended concrete was subsequently tested for compressive strength, water absorption and consistency and workability in compliance with the American Society for Testing Materials (ASTM,).The results generally showed that both compressive strength and the water absorption of the test cubes increase with the level of FESA utilization. At 28 days curing particularly, the maximum values of compressive strength and water absorption of the FESAC were 27.92N/mm2 and 0.93% respectively. These were attained between 15% and 20%cement -ash substitution. Although, the workability of the fresh fowl egg shell ash-blended concrete varies inversely as the percentage of blending, a medium workability (true slump=4mm) is achievable at 15% cement-egg shell ash substitution. The study concluded that the germane properties of fowl egg ash – blended structural concrete under investigation are not compromised at 15% FESA cement – substitution.
