EFFECT OF PARTIAL REPLACEMENT OF COARSE AGGREGATE WITH PALM KERNEL SHELL ON COMPRESSIVE STRENGTH OF CONCRETE
Abstract
This report is a comprehensive summary of the research carried out by myself on the effect ofreplacement of coarse aggregate with palm kernel shell, on the compressive strength of concrete.This study was carried out to investigate the effect of partial replacement of coarse aggregate(granite) with Palm Kernel Shell on compressive strength of concrete. Concrete specimens wereprepared with a mix ratio of 1:2:4 (Cement: Sand: Granite and Palm Kernel shell). Water/cementratio of 0.55 was adopted for all relevant laboratories testing. The granite was partially replacedwith PKS at different percentages of 5, 10, 15, 20 and 25% by weight of the dry sample. The testconducted include: Sieve analysis of Granite (CA), Sand (FA) and Palm Kernel Shell (PKS),Specific gravity of PKS, SD and GT, Slump (Workability) test of fresh concrete, Water absorptiontest of Granite (GT) and Palm Kernel Shell (PKS), Density test of Granite (GT), Sand (SD) andPalm Kernel Shell (PKS) and Compressive Strength test of hardened concrete cubes.
