Abstract :

Palm kernel shell ash (PKSA) was used as admixture in cement mortar to determine the effect of PKSA on the properties of cement mortar. An experimental investigation was carried out to establish the trend of the properties changes with reference to the proportion of PKSA added. The ash was used at additional levels of 0.5 to 3.0% by weight of cement. Physical tests on cement were performed on cement/PKSA mixes. The consistency and setting times all increased with increase in the level of PKSA. Twenty-eight (28) days saturated compressive strength of the mortar cubes were in the range of 24.76 to 25.42MPa for replacement level 0.5 to 3.0%.while it gave a reading of 26.89MPa at no addition (0.0% PKSA). These results confirm that the combined use of cement and PKSA between 0.5 to 3.0% addition level) have no significant influence on the physical properties and on the compressive strength of cement mortar and could safely be used.
