dc.description.abstractThis study examined the influence of varying palm kernel shell ash (PKSA) content, as blended cement on the compressive strength of mortar cubes. Palm kernel shell ash was used as a substitution for ordinary Portland cement (OPC) from 10 to 40% at 10% intervals using mix ratios 1:2.75 and 1:2.36 together with river sand. The compressive strength of the blended mortar was tested for different curing ages, with the strengths at ages 14 and 28 days reported. Result showed that the compressive strength of PKSA-OPC mortar increased with curing age but decreased with increasing percentage of PKSA compared to the compressive strength of the control. For ratio 1:2.75, the compressive strength of the control with 0% PKSA was 13.57 N/mm2 while mix ratio 1:2.36, yielded 12.10 N/mm2 at 28 days respectively. This class of strength could be used for mortar type N, O and S classification. The compressive strength of 8.12 N/mm2 was obtained for 10% replacement at 28 days of age with percentage strength reduction to the control of 40%, while 20%, 30% and 40% substitution of cement with PKSA yielded compressive strength of 8.65 N/mm2, 7.43 N/mm2 and 2.97 N/mm2 respectively with percentage strength reduction to the control of 36%, 45% and 78% respectively. This research showed that PKSA has the potential of being used as a substitution of cement up to 40% to produce blended mortar.en_US
