Abstract
Concrete may be melted to form a glass product. Methods and batch compositions including concrete may be used to produce amorphous silica materials including, but not limited to, glass, container glass, fiber glass, glass bead, glass spheres, sheet or plate glass, glass aggregate, glass sand, abrasives, proppants, foamed glass, and manufactured glass articles. The initial processing steps include preparing a melt batch comprising concrete and, optionally, other components, melting the melt batch, and cooling the melted melt batch. Further processing steps may be utilized to produce the glass article.
Claims29
A method of producing an amorphous silica material, comprising:
- preparing a batch comprising concrete;
- melting the batch in a furnace to melt effluent;
- cooling the melt effluent to form amorphous silica particles, mass or product;
- and
- crushing the amorphous silica particles, mass or product to form glass particles.
A method of producing an amorphous silica material, comprising:
- preparing a batch comprising concrete and glass cullet;
- melting the batch in a furnace to melt effluent;
- and
- cooling the melt effluent to form amorphous silica particles, mass or product.
A method of producing an amorphous silica material, comprising:
- preparing a batch comprising concrete and an iron oxide;
- melting the batch in a furnace to melt effluent;
- and
- cooling the melt effluent to form amorphous silica particles, mess or product, wherein the iron oxide is magnetite.
A method of producing an amorphous silica material, comprising:
- preparing a batch comprising concrete and limestone;
