dc.description.abstractModern scientific and technological move towards concrete production is aimed at achieving sustainable and affordable concrete construction. This move has led to the search for non-conventional local supplementary cementitious materials (SCM’s) including the possibility of using industrial and agricultural based pulverized and combustible wastes in concrete construction. In this study, an experimental investigation was conducted on the potential use of sheanut shells ash, derived from the combustion of sheanut shells – an agro-based waste, as partial replacement of cement in concrete. The cement content in the concrete mix was partially replaced 0%, 10% and 20% by mass with sheanut shells ash. The effect of the ash on setting time and workability were examined. Five concrete cubes were prepared for each of the replacement levels from which three cubes were randomly selected from each replacement level and tested for compressive strength at three stages of curing age (14, 28 and 90 days). There were high and minimal reductions in the compressive strengths of the experimental cubes over the control cubes at the 14 and 28 curing age respectively. However, there was a significant increase in strength of the experimental cubes over the control cubes at the 90 days curing age. Though the ash has an improved increasing effect on strength, the findings will limit it use in situations where long term strength development is required.
