The low strength can be due to the low workability and lower compaction of the mortar having high percentage of quarry dust powder. 2. With an optimum replacement level of 30%, a considerable increase in compressive strength and modulus of elasticity were observed, along with a major decrease in the rate of abrasion was noted.
