| The strength properties of mortar mainly depend on the materials used for casting. Each material has its own importance for cement mortar strength. In this research, quarry fines, a waste by-product, replaced a portion of fine aggregate in mortar. This research focuses on compressive strength of cement mortar using American Society for Testing and Materials standards. The specimens were cast in standard 2"x 2" inch molds. The compressive strength of blocks with replacement of fine aggregate by quarry fines at 15%, 25%, 30%, and 50% was tested at 7, 14 and 28 days of curing. The results were compared with a control group. Compressive strength of mortar blocks increased by comparison to the control group for all percentage replacement of fine aggregate by quarry fines. The mortar batch using 50% quarry fines produced the higher compressive strength results at 28 days of curing. Quarry fines were found to have similar specific gravity and absorption to fine aggregate. Keywords: Quarry Fine, Fine Aggregate, Binding Material, Mortar and Compressive Strength. |
