Silica sand with 99.5 simply means that if you take 100 grams from the bulk of that sand 99.5 grams must be SiO2.Similarly if you take 1000 grams of the same sand, 995 grams must be SiO2.This also means that 0.5 will be unwanted material, 99.5 is fairly high purity.
Crystalline silica is a natural mineral formed within the earths crust. It can be found in sand and stone, and is used in artificial products like concrete, ceramics, bricks, and glass. When these are manufactured, sawed, or drilled, Crystalline silica particles 100x smaller than sand become respirable, which is dangerous to exposed workers.
TSI instruments use light scattering photometric technology to measure the amount of total respirable dust in the air. When properly calibrated, the instrument can determine the amount of crystalline silica in the aerosol sample. The photometric calibration factor adjusts the photometric reading of the instrument to the known silica content in ...

To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sandlime ratio of 10 or 20. The mix is then compressed into moulds and autoclaved at about 170 C 340 F for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.
Silicosis in Dental Laboratory Technicians --- Five States, 1994--2000. Silicosis is a debilitating, sometimes fatal, yet preventable occupational lung disease caused by inhaling respirable crystalline silica dust. Although crystalline silica exposure and silicosis have been associated historically with work in mining, quarrying, sandblasting ...
Crystalline silica is a common mineral found in many naturally occurring materials and used in many industrial products and at construction sites. Materials like sand, concrete, stone and mortar contain crystalline silica. Crystalline silica is also used to make products such as glass, pottery, ceramics, bricks, concrete and artificial stone.

Sand reclamation has become a necessity in no-bake operations, particularly given the current challenges regarding the cost and availability of new sand. Foundries can no longer afford to operate with new sand alone and most are exploring how best to economically integrate sand reclamation systems into their processes. For a reclamation plant to realise the

Bhagias Non-occupational exposure to silica dust, Indian Journal of Occupational amp Environmental Medicine 2012 Sep-Dec 163 95100, available through the NIH Silica is a ubiquitous mineral-- most sand is silica-- found in abundance almost everywhere.
An estimated 2 million construction workers in the United States have been exposed to respirable silica dust, according to the Occupational Safety and Health Administration. Thats why OSHAs Respirable Crystalline Silica standard requires that employers limit workers exposure to silica and take other steps to protect workers. Silica dust appears in asphalt, concrete and rocks,
Silica sand should not be used as an abrasive blasting material. See OSHA standard PB-246-697 and OSHA Crystalline Silica Exposure Health Hazard Information in the Safety section of our website. All of Clemtexs Abrasives sold abide by OSHAs standards and contain less than 1 free silica.
New regulations are changing standards for silica dust exposure. OSHA 29 CFR 1926.1153 d2v limits exposure the time of exposure to crystalline silica to 50 micrograms per cubic meter of air. As this new rule for respirable crystalline silica exposure takes effect, customers have asked the RAECO Rents team for help with the proper personal monitoring instruments.
