Replacement of quarry dust with fine aggregate at a ratio of 30 percent produces the best results, but beyond that, the strength obtained gradually diminishes. It has been shown that increasing the proportion of quarry dust in concrete may increase its workability by as much as thirty percent for M40 grade concrete.

sand as fine aggregates in the production of concretes especially in Concrete. Quarry dust, a by-product from the crushing process during quarrying activities is one of such materials. 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

The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity.

Quarry dust is a waste obtained during quarrying process. It has very recently gained good attention to be used as an effective filler material instead of fine aggregate. Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the partial replacement for natural river sand.

This research studies the corrosion on quarry dust mortars due to sulfuric acid. By fully using quarry dust instead of sand and w/c = 0.45, the mortar specimens are formed and cured for 28 days before immerse them into 5 % (W/W) of sulfuric acid solution. From the results, it is found that quarry dust mortars can resist the corrosion better than …
