In this paper, quarry stone dust was used as an alternative to natural sand for concrete mix proportion. Moreover, the effect of partial to full replacement of natural river sand with this type of aggregate on the workability, compressive strength and flexural strength of concrete was studied. The results showed that although the use of quarry stone dust caused a reduction in slump value, compressive and flexural strength were comparable to the case of using natural sand. | Influence of partial and full replacement of natural sand with quarry stone dust on properties of fresh and hardened concrete
