The Effect of Untreated Dura-Palm Kernel Shells as Coarse Aggregate in Lightweight Pervious Concrete for Flood Mitigation

This research aimed at ascertaining the performance of raw dura species Palm Kernel Shells (PKS) in comparison to a different PKS (tenera) as replacement for known aggregates pervious lightweight concrete. Using limestones aggregates, control concrete was batched, and relevant tests were conducted. Major conducted on composites concerned compressive, tensile, flexural strength, well permeability, densities, absorption. Logistic constraints transporting dura-PKS limited quantity needed ascertain variety replacements dura-PKS. With 25% be most suitable ratio related investigations, we adopted that compared extreme 100% The revealed by resulted high porosity although resistances compression, tension, loads read low same mixture. Instead, yielded optimum water permeability rate compressive stresses. However, flakiness index recorded almost half tenera not reflected mechanical properties results gave relatively lower strengths. case do differ significantly tenera-PKS terms strength permeability.
