quarry dust has rough surface textures and angular shape due to crush nature of the aggregate. Rough surface texture provide better interlocking and good bond between the cement paste and the aggregate. Maximum percentage of voids in quarry dust ranges from 3840% [1][2], Due to angular nature of the aggregate (surface

· Further when fly ash is partially replaced with cement from 0 to 30% in mortar with 20% quarry dust (QF series), there is an overall increase in strength at 3 days, 7 days, and 28 days of age. The drop in compressive strength due to conversion reaction decreases with increase in fly ash content for a given water to powder ratio.
