Application

Crushed dust-like quartz is used as a mineral agent added to oil-well and construction cements in fractions of up to 30%. This additive is used as a filler bettering the strength properties of cement mixture and allows cutting the consumption of cement.

 

Packaging

Natural siliceous materials are packaged in 25-kg polypropylene bags with a polyethylene liner or in big bags.
