Abstract: The suitability of quarry dust as alternative material for the river sand in concrete manufacturing is studied. M25 grade concrete was prepared with 0%, 20%, 40%, 60%, 80% partial replacement of sand with quarry dust. The physical properties of quarry dust namely specific gravity; water absorption; silt content; and fineness modulus were measured using standard tests. This was followed by compression, split tensile and bending tests on cubes, cylinders and RC beams respectively to study the strength of concrete made of quarry rock dust. The results were compared with the conventional concrete (0%). The results showed that with increasing proportion of quarry dust, the strength increased to peak value (at 40%) followed by a subsequent drop in strength and a decreased workability.
