Sand is obtained from river beds, and is its availability is becoming challenging at reasonable price. In order not to compromise strength of building during construction, quarry dust come handy as an equal substitute without threat to quality at the same time rendering good strength to whatever construction project quarry dust is used for. Highway Construction
natural river sand has become scarce and very costly. Hence we are forced to think of alternative materials. The Quarry dust may be used in the place of river sand fully or partly. A comparatively good strength is expected when sand is replaced partially or fully with or without concrete admixtures.
The Hazards of Dust from a Pit/Quarry Operation. Dust or airborne particulate matter (PM) varies in size. Total Suspended Particulate (TSP) refers to dust less than 100 microns in diameter. Large particles tend to settle quickly, smaller more harmful particles can be carried great distances. Dust is produced from blasting, crushing, screening and stacking operations as well as conveyor belts and loader and truck
highly scarce and expensive. Therefore looking for an alternative to river sand has become a necessity. Hence, the crusher dust which is also known as Quarry dust and Marble powder can be used as an alternative material for the river sand. Quarry dust and Marble powder contains similar properties as that of river sand and hence accepted as a
