| dc.description.abstract | This study investigates the potential usefulness of periwinkle shell as an alternative replacement of coarse aggregate in concrete work. The mechanical properties of concrete with fine and coarse aggregates components fully and partly replaced with lateritic sand and periwinkle shell was investigated. A working sample of one hundred and thirty five concrete cubes of 100mm dimensions were produced and cured in water for 7, 14 and 28 days. The fine aggregates and coarse aggregates were replaced with lateritic sand and periwinkle shells respectively at 10%, 20%, 30%, 40% and 100%. The mix proportions adopted for this work was 1:1½:3, 1:2:4 and 1:3:7 with water/cement ratio of 0.65. the results indicates that through partial replacement the concrete composed of up to 20% of lateritic sand and periwinkle shell developed a higher compressive strength for the curing ages of 7, 14, and 28days independent of the mix ratios than concrete containing lateritic sand and periwinkle shell at 100% full replacement.The study therefore recommends that 20% lateritic sand and periwinkle shell replacement for fine and coarse aggregate in concrete is suitable for use as low strength lightweight concrete. | en_US |
