Welcome to Vitro Minerals
Vitro Minerals is a leading manufacturer of glass powders and sands made with plate, container, and specialty glasses.
The powders are widely used in the coatings, plastics, rubber, and adhesives/sealants industries to provide functional fillers constituting 100% recycled content. Other applications include ceramics, glazes and frits. Glass based pozzolans also act as an excellent mineral admixture providing a 100% “green” construction material that helps contribute to the sustainability of cement and concrete.
Glass powders used as pozzolans are making strong gains in the concrete industry. A pozzolan is an amorphous material that reacts with lime when water is added to cement powder. The reaction results in additional calcium silicate binder to make the concrete stronger and more durable. Vitro glass pozzolans include VCAS, an E Glass; ACAS, a bottle glass, and HR 50, which is a fumed nanosilica for very high reactivity. After years of test work and rapidly growing acceptance, glass pozzolans are now developing their own standalone ASTM standard.
Specialty glasses include No, 1, Type 33 borosilicate glass equivalent to Pyrex 7740, as well as Kimble, Schott, Kavalier, Nipro, & Gerresheimer. Another specialty glass is E- Glass, derived from fiberglass reinforcements, sold under our VCAS trademark. Vitro also produces Fuzed Quartz chips and submicron powders known as RS 50. Neutral pH glass is any Vitro grade treated with a proprietary process to a stable pH between 5-8 as required.
Bottle glass is widely used as recycled glass specially engineered for dustless blasting and other substrate cleaning operations where a clean surface is prepared with silica free, environmentally friendly media. Bottle glass powders, known as ACAS, are also used in pozzolands in concrete.
