Abstract

This paper presents the results of laboratory tests conducted to investigate a concrete made with laterite rock coarse aggregates. The structural properties considered were strength and elasticity. Laterite concrete mix proportions of 1:3:6, 1:2:4 1:1½:3 by weight of cement, river sand and laterite rock respectively at varying water/cement ratios of 0.55-0.90 were used. The results established an optimum water/cement ratio of 0.75, 0.60 and 0.55; with characteristic strengths of 12.00N/mm2,18.69N/mm2 and 22.88N/mm2 for mix 1:3:6, 1:2:4 1:1½:3 respectively. Flexural and splitting test results were about 6 - 21% of the compressive strength of the laterite rock concrete. The static modulus elasticity of laterite rock concrete is 22.72kN/mm².
