2.3.2 CHEMICAL PROPERTIES OF QUARRY DUST- The Chemical properties of quarry dust are determined by much result which is obtained by laboratory testing. These test are performed as per Indian standard code S.NO. CONSTITUENTS QUARRY DUST NATURAL SAND IS CODE 1 SiO2 62.58 80.78 IS 4032-1968 2 Al2O3 18.60 10.52 IS 4032-1968
Stone dust is also known as rock dust or quarry dust, and some products just have the brand name. The stone dust is collected using a screen that keeps the larger pieces of crushed stone above the screen while allowing the rock dust to fall through. This process is the reason why stone dust is often called quarry screenings.
Properties of cold bonded quarry dust coarse aggregates . Sep 01, 2015amp 0183amp 32Quarry dust collected from a granite quarry is used. Its chemical composition is given in Table 1. There are more sili es in quarry dust and compared to other compounds. It is expected that the sili es improves the bonding process in the pelletisation process.
