Granite fines or rock dust is a by-product obtained during crushing of granite rocks and is also called quarry dust. Concrete containing quarry dust as fine aggregate is promising greater strength, lower permeability and greater density which enable it to provide better resistance to freeze and thaw cycles and durability in adverse environment.

The quarry dust concrete and river sand concrete shoed slump test values of 80 mm and 60 mm, respectively. And, fresh concrete mix of quarry dust concrete showed lower workability than river sand concrete for 1:2:4 mix ratio and water-cement ratio of 0.55. The higher slump interposed for quarry dust may be due to higher sand content in quarry dust.
