About Silica Sand . Silica Sand--also known as quartz sand, industrial sand, white sand--is formed from quartz that has been broken down through wind and sea erosion. Commercial silica sand is mainly used in construction materials like mortar, flooring, cement/asphalt, shingles, and sealant, as it is resistant to corrosion and the elements.
Silicosis is a progressive, debilitating and sometimes fatal lung disease caused by breathing silica dust from cutting, drilling, chipping or grinding materials such as granite, sandstone, slate or artificial stone. The dust gets trapped in the lung tissue, causing inflammation, scarring and permanent damage.. Silicosis is a job-related lung disease and has no cure.
