TESTING PROCEDURE Fine aggregate 28 days A. Fresh concrete workability Sand: Quarry dust Compressive strength ( in MPa) To determine consistency of concrete, Slump test was M20 M25 conducted with varying water content and a particular water 100:0 17.63 24.37 cement ratio (w/c) which gives the slump of 60mm was selected 90:10 18.29 24.50 from graph.

quarry dust), M 4 (40% quarry dust), M 5 (50% quarry dust) respectively. The variations of slump value with quarry dust percentage are shown in Figureure 1. It is observed that the slump value increases with increase in percentage replacement of sand with quarry dust for the same w/c ratio. Concrete does not give adequate

4. The physical and chemical properties of quarry dust satisfy the requirements of sand. 5. Use of quarry dust in concrete help in workability of concrete. 6. Quarry dust is a waste product from stone crushing industry and available almost free-of-cost, as partial replacement for river sand. REFERENCES

Powder (CPR)/Quarry dust (QD) as fine aggregate in cement concrete, replacing natural sand. The study on concrete includes determination of compressive strength and split tensile strength of different grades of concrete. Properties of aggregate affect the durability and performance of concrete…

Quarry Rock Dust concrete are quite large to the shrinkage strain of Conventional Concrete. However, at the later age, they have shown equal strain than Conventional Concrete. Durability of Quarry Rock Dust concrete under sulphate and acid action is higher inferior to the Conventional Concrete Permeability Test results clearly demonstrates that

Partial Replacement of Sand with Quarry Dust in Concrete. -The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete.

Granite fines or rock dust is a by-product obtained during crushing of granite rocks and is also called quarry dust. In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available ...

Apr 09, 2015· Duarte residents challenge Vulcan's assertions, however, saying the amount of dust has increased over the past year since Vulcan has started work at the quarry. Vulcan's plan will shift its mining operations from 80 acres on the eastern end of the 270-acre property to 80 acres on its western end, under a permit through 2038 to mine 190 ...
