Alternatively, quarry dust produced (about 10–15%) from the extraction process of rock at quarries could be used to replace sand for the production of concrete. Although quarry dust did not possess similar granular shapes as river sand, the other physical and chemical compositions of quarry dust seem to be comparable to river sand The mix proportion of concrete is adopted for M50 grade concrete. The average strength of the 3rd day, 7th day, and 28th day of concrete replaced quarry dust in a range of 0–100% shown in Table 2.

Dust emission from crushing of hard rock aggregates

Local dust sources, such as hauling, impacted the results inside the quarry. Crushing produced more dust compared to comparable studies for drilling. The dust concentrations at the limestone quarry were approximately 50% of concentrations measured at quarries with granitic rocks.Suppress weeds; Improve crop quality and flavor; and. Increase brix. Rock dust is also a great additive to acidic soils, as it can help increase soil pH, thus reducing acidity.

Improving Swelling and Strength Behavior of Black Cotton

The dust produced due to quarrying activities is detrimental to the environmental pollutions concerning both air and land where it gets deposited. The gradation and physical properties of quarry dust are found analogous to that of natural sand [6, 13, 14]. Therefore, these can be used as an alternative to natural sand for soil stabilizationCrushing produces mainly coarse (TSP and PM 10) dust particles which settle near the dust source. The mass concentration of coarse particles varied from few tens of μg/m 3 to over 6 × 10 3 μg/m 3 downwind from the crusher. The mass concentration of fine particles (PM 2.5 and PM 1) ranged between ten μg/m 3 and few hundreds of μg/m 3Dust emission from crushing of hard rock aggregates

Quarry dust has particle sizes in the range of 0.05-5 mm and forms around 20-25% of the total output of rock crushing [6,10]. Large volumes of quarry dust are produced by rock quarrying industries which cause environmental problems. Only a little fraction of the quarry dust is used as filler in wearing courses of asphalt pavements [9].
