Effect of Palm Kernel Shell on the Compressive Strength and Saturated Surface Dry Density of Stabilized Soilcrete
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 5
Abstract
This research studies the effects of palm kernel shell on the compressive strength and saturated surface dry density of stabilized soilcrete (SC). Preliminary tests were carried out for identification and classification of laterite and palm kernel shell (PKS). Compressive strength (CS) test on different percentage of PKS, and effect of cement aggregate ratio (CAR) on the saturated surface dry density (SSDD) of the stabilized palm kernel shell soilcrete were also carried out. A uniformly graded clayey SAND (SCl) laterite with low plasticity and uniformly graded palm kernel shell (PKS) with maximum grain size of 13.2 mm was used. The stabilized PKS soilcrete blocks were produced using CAR of 1:9, 1:12.33 and 1:19 at 10%, 20%, 30%, 40% and 50% replacement of laterite with PKS, with varying w/c ratios of 0.75, 0.77, and 0.80. Compaction pressure of 4.14 MPa was gradually applied to produce 150 × 150 × 150 mm SC cubes. A total of 162 cubes were produced from 54 mix ratios and 3 cubes for each mix ratio; the average compressive strength (CS) and saturated surface dry density (SSDD) were determine after 28th day curing using. The results from the compressive strength at different replacement levels shows that, the optimal CS value occurred at 20% replacement of laterite with PKS with the numerical value of 1.68 MPa at 1:9 CAR and 0.80 w/c for compaction effort of 4.14 MPa. The SSDD value for CAR of 1:9, 1:12.33 and 1:19, at 0.75 w/c, 0.77 w/c and 0.80 w/c decreased as the %PKS content increases. Similarly, the SSDD decreases as the CAR increases and the maximum SSDD values was obtained at 1:9 CAR for 0.75, 0.77 and 0.80 w/c. The following conclusions drawn shows that the CS of soilcrete block (SCB) increased as %PKS increased from 0 to 20% and reduced with further increase in PKS content while the SSDD decreased as %PKS increased from 0 to 50%. Likewise, it was observed that increase in CAR reduced the saturated surface dry density (SSDD) at the same w/c and compaction effort. The optimal percentage replacement of laterite with PKS in SCB was 20%, which implies that the PKS possesses the potential for use in the production of compressed stabilized SC and hence recommended for use.
