Various mixing ratios of silica sand and clay were prepared. Each silica sand and clay composition was mixed together in the dry state for 10 min in the first instance to facilitate thorough mixing. Five percent tempering water was gradually added to the mixture while mixing was done again for another 10 min.

Crystalline silica, in the form of sand, can cause silicosis (an incurable but preventable lung disease) when inhaled by workers. Sand is a main ingredient used in the fracking process. The National Institute for Occupational Safety (NIOSH) collected air samples from 11 fracking sites around the country. All 11 sites exceeded relevant occupational health criteria for exposure to respirable crystalline silica.
