Density Quarry Dust Kg M-HN Mining Machinery Manufacturer

Jan 01, 2012 The addition of quarry dust increases the fresh density. The hardened density at 28 days of the CLSM mixes varies from 1414 kg/m 3 to 2123 kg/m 3. Hardened density is more for mixes with BA/QD ratio of 0/100, and less for mixes with BA/QD of 100/0. Hence it is clear that the addition of quarry dust increases the hardened density of CLSM.
