(PDF) Study on Compressive Strength of Quarry Dust as Fine …
Quarry dust fine aggregate decreased the compressive strength due to deficient grading and excessive flakiness. The w/c ratio and slump value increased with the replacement of sand, Voids present in quarry dust mortar were lesser as compared to that of sand hence higher compressive strength. A comparatively good strength is expected when sand ...

Suitability of Crushed Stone Dust as Fine Aggregate in Mortars
The purpose of this study was to investigate the possibility of using crushed stone dust as fine aggregate partially or fully with different grades of concrete composites. The suitability of crushed stone dust waste as fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete.

INTRODUCTION. Desert dust is a key component of the Earth's climate system, accounting for ~70% of the mass and ~25% of the shortwave (SW) radiation extinguished by aerosols in the atmosphere ().The impacts of dust on the Earth system, as a result of interactions with radiation, clouds, and biogeochemistry, are sensitive to the sizes of dust particles in the atmosphere ().

IDEM: Air Compliance: Fugitive Dust
Fugitive dust does not include fine particles that originate from a stack, vent, or chimney. The state rules on fugitive dust, which apply to all sources of dust (particulate matter), are found in the Indiana Administrative Code at 326 IAC 6. A source is considered to be generating fugitive dust if the dust is visible crossing the property line ...
