18.12.2017 · This research investigated the potential of cement stabilized shale quarry dust for possible use as road foundation material. From the results, the shale consists mainly of SiO2 (27.760.1%), Al2O3 (7.3017.9%), CaO (3.9132.3%) and LOI (4.9318.8%). The shale quarry dust (SQD) in its natural state had an average liquid limit (LL) as 38%, plasticity index (PI) as 24% and fines fraction

Low-Toxicity Dusts Current Exposure Guidelines

18.07.2013 · Low-toxicity dusts include all poorly soluble, nonfibrous dusts that, at low levels of exposure, have negligible toxic effect on the body but if inhaled in sufficient quantity, accumulate and cause injury in the terminal airways and proximal alveoli, leading to inflammation with subsequent development of COPD and, in coalminers at least, pneumoconiosis. By this definition, low-toxicity dusts

31.12.2012 · The filtration properties of Indian fabrics were measured using modified respiratory protective device (RPD) tests, to match conditions in Indian quarries. Results were compared to those of dust masks meeting Australian and International standards. Four layers of loose weave fabrics were found to perform best, but would still be insufficient for use at sites with highly hazardous dusts.
