Abstract
The excruciating cost of cement has been constituting serious threat to the provision of safe, adequate and affordable housing for low income earners in Nigeria. Consequently, the search for cheaper alternate materials has become imperative. It is against this backdrop that this work investigated the potentials of snail shell ash (SSA) as partial replacement of cement in concrete. Towards this end, graded levels of snail shell ash (0%, 5%, 10%, 15%, and 20%) all passing through 75um sieve were used to prepare 1:2:4 concrete mix of water cement ratio of 0.5. Mechanical and physical properties of the resulting SSA blended concrete, such as workability, water absorption, density and compressive strength were determined in accordance with British Standards BS1881. The results showed that at 20% SSA replacement, the concrete has the lowest water absorption rate of 0.12% and the highest of 0.74% respectively, at 20% and 5% SSA% replacement. Furthermore, average density at 28days was shown to be 2376.30 Kg/m3while 28days compressive strengths were 23.92N/mm2 and 24.63N/mm^2 respectively, at 15% and 20%SSA replacement. The study concluded that after 28days of curing, SSA concrete could be used as normal weight structural concrete provided that application level of SSA does not exceed 20%.
