Abstract: The demand to make this material lighter has challenged scientists and engineers alike. The challenge in making a lightweight concrete is decreasing the density while maintaining strength and without adversely effecting cost. One such alternative is coconut shell (cs), as coarse aggregate in the production of concrete. Even though coconut shell possesses several desirable properties, its relative low tensile strength and deformation properties prompted many researches to work on to improve these properties. One such development of improving or modifying the properties of concrete is by supplementing the mineral admixtures with coconut shell concrete. Experimental investigations and analysis of results were conducted to study the compressive and flexural strength behavior of concrete with varying percentage of mineral admixtures. The concrete mix adopted were m25 with varying percentage of mineral admixtures ranging from 2%, 4%, 6%, 8%, 10%, 12%, 14%, 16%, 18%, 20%, 22%, 24%, and 26%. On the analysis of result the concrete with mineral admixtures in coconut shell had improved performance as compared to the ordinary concrete.
