Abstract

This study is focused on assessing the effectiveness of palm kernel shell (PKS) as partial replacement aggregates for normal concrete. The tests carried out on PKS concrete at a constant water cement ratio of 0.5 with mix ratios 1:2:4 and 1:1 𝟏/𝟐 : 3 with PKS varied from 0%-30%. The results of the slump and compaction factor test showed that all mixes were workable for all replacement levels considered. The compressive strength values obtained ranges between 32.2N/mm²-13.4N/mm² with implies that, the addition of PKS in the production of light weight concrete is suitable for both mix ratios. The cost analysis also revealed reduction in cost by 6.5%, 13% and 19.5% for PKS replacement at 10%, 20% and 30% respectively. It is concluded that PKS is effective, less expensive as partial replacement aggregates and also reduces environmental pollution.
