Second, because crushed limestone has a lighter unit weight than gravel, it will require about 12% less crushed limestone than gravel to mix a cubic yard of concrete. Additionally, crushed limestone concrete is easier to saw through than gravel concrete. This is because most gravel is silica. Silica is almost impossible to cut with a steel saw.

Silica gel is a desiccant which means it absorbs and holds water vapor. That is why the most common use for silica gel is found in storing and transporting goods: Manufacturers use silica gel to keep goods from spoiling, molding, or degrading due to humidity.

Crushed glass blasting media is an engineered "sandblasting" media manufactured from Recycled Bottle Glass. Crushed glass can be used as a direct replacement for most hard abrasives, including silica-sand, Olivine, lava, coal slag (aka Black Beauty), and aluminum oxide. Crushed Glass is approved for use in numerous federal and state ...

It only takes a very small amount of the very fine respirable silica dust to create a health hazard. Recognizing that very small, respirable silica particles are hazardous, OSHA regulation 29 CFR 1926.55 (a) requires construction employers to keep worker exposures at or below a Permissible Exposure Level (PEL) of 50 µg/m3.

Crushed glass can replace OSHA-regulated silica sand for abrasive blasting on construction sites. Allows contractors to use a CARB certified, chemically stable, inert media to remove paint and powder coating. When properly used, crushed glass is mild enough to use around environmentally sensitive areas and delicate jobs.
