Sieve analysis for river sand and quarry dust Particle size distribution test was done on both the River sand and the quarry dust in accordance with (BS882, 1983). Sandcrete block production 450 x 225 x 225 mm hollow blocks were produced and used for this research. The constituent materials include cement, sand, quarry dust and water.
Quarry rock dust (QRD), a waste obtained during the quarrying process is a significant source of air pollution yet has the potential of becoming a sustainable and economical alternative to sand in concrete. Studies confirmed that replacing sand in conventional concrete with QRD increases its durability and robustness by ten percent.

It was reported that quarry dust as a replacement for fine aggregate in concrete increased the strength of concrete tremendously by up to 8–20% . Hamid et al. [ 29 ] highlighted that the addition of quarry dust above 50% as replacement material will yield a negative effect on concrete compressive strength and workability.
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.
It improves the mechanical property of concrete. Usage of quarry dust it will also reduce the cost of concrete because it is a waste material from quarry. Dust in concrete will also reduce the disposal problem. 4. Objectives 1) To study the behaviour of concrete on which fine aggregate is replaced with quarry dust along with super plasticizer.
In this paper, we have investigated the study of quarry rock dust as partial replacement of fine aggregate in concrete. Mix design has been developed for M20 grade using IS design for conventional concrete and replaced mix. Specimens on cubes, cylinders and beams were prepared for both conventional and 20%, 40%, 60% replacement with quarry dust.

to study the effect of partial replacement of fine aggregates by quarry dust and cement by fly ash on cement concrete. 1.2 NEED FOR INVESTIGATION Quarry Dust These residues are generally less than 1% aggregate production in the normal concrete. The introduction of quarry dust for mixing is limited due to its high fineness.
found that the compressive and flexural strength of concrete made of Quarry Rock Dust are nearly 10% more than the conventional concrete (Suribabu et al., 2015). In the present study it is proposed to investigate the optimum replacement of river sand with stone dust for concrete in term of compressive strength performance at 7 days and 28 days. II.
