Therefore, Quarry dust has been proposed as an alternative to the river sand in concrete mix, and it gives an additional strength to the concrete. This utilization of Quarry Dust by replacing sand would also reduce the pollution in environment and also reduce the cost of concrete. ABSTRACT This paper describes the experimental study of High-Performance concrete with quarry dust as fine aggregate in addition of steel fibre. To over-come the difficulties due to excessive sand mining, quarry dust was used as fine aggregate. Quarry dust is the fine material, produced from gravel crushers.
Quarry dust For Partial Replacement The bricks, tile other lightweight materials are made from the quarry dust. The chemical composition of quarry dust is mostly the same as granite rock. So the strength and durability of quarry dust are good to use in concrete. Sand in the future, it is very important to find Sand Alternate. The lack of sand directly affects the construction work. Many researchers are finding different materials to replace sand and one of the major materials is quarry stone dust. By the using of quarry stone dust make a proper mix of concrete with a satisfactory strength.
