QUARRY DUST: rushed rock aggregate quarrying. C generates considerable volumes of quarry fines, often termed "quarry dust". Quarry dust can be defined as residue, tailing or other non-voluble waste material after the extraction and processing of rocks to form fine particles less than 4.75mm. Test on Materials. Test on Aggregate and Sand. 1.

A possible alternative to natural sand in production of concrete is quarry dust, a by-product of rock quarrying. 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 ...
