Abstract

The use of pulverized glass having a particle size of 0 nm to 100 μm as an ingredient in a composite material, said composite material is obtained by mixing a base component and a hardener, is disclosed. The pulverized glass is useful in composite materials, such as either a cement-based material which is to be mixed with water as a hardener or in epoxies, acrylics, polyurethanes, butylenes or silicones.

Claims

1. A composite material comprising pulverized glass with a particle size less than 100 microns, wherein the most abundant particles of pulverized glass are in the range of 0.1 micron to 0.4 microns and a base component selected from the group consisting of hydraulic cement, epoxy, acrylic, polyurethane, butylene, or silicone;

and water if the base component is hydraulic cement.

2. The composite material according to claim 1, wherein the pulverized glass particles comprises between 2 to 94 wt % of the composite material.

3. The composite material according to claim 1, wherein the hydraulic cement is Portland cement.

4. The composite material according to claim 1, further comprising quartz sands of particle size of 0.25 to 4 mm and/or microsilica of particle size 0.1 to 0.4 microns.

5. The composite material according to claim 1, wherein the base component is polyurethane.

6. The composite material according to claim 1, further comprising fibers.

7. The composite material according to claim 1, wherein the fibers are glass, polymer, steel, carbon, or cellulose containing fibers.

8. A composite mix for use in manufacturing a composite according to claim 1, wherein the base component comprises:

greater than 0 kg/m3 to 400 kg/m3 Portland cement;

75 to 150 kg/m3 quartz sand of particle size 0.25 to 1 mm;

400 to 600 kg/m3 quartz sand of particle size 1 to 4 mm;

50 to 1100 kg/m3 pulverized glass of particle size less than 100 microns;

optionally less than or equal to 35 kg/m3 fibers; and

optionally plasticizers.

9. A composite mix according to claim 8, wherein the fibers are selected from the group consisting of glass, polymer, steel, carbon, or cellulose containing fibers.

10. A method of making a composite material comprising mixing pulverized glass as a base component having a particle size less than 100 microns and a base component selected from the group consisting of hydraulic cement, epoxy, acrylic, polyurethane, butylene, or silicone;

and water if the base component is hydraulic cement.

11. A composite mix for use in manufacturing a composite material comprising pulverized glass with a particle size less than 100 microns, wherein the most abundant particles of pulverized glass are in the range of 0.1 micron to 0.4 microns and a base component selected from the group consisting of hydraulic cement, epoxy, acrylic, polyurethane, butylene, or silicone;

and water if the base component is hydraulic cement.

12. The composite mix according to claim 11, wherein the pulverized glass particles comprises between 2 to 94 wt % of the composite material.

13. The composite mix according to claim 11, wherein the hydraulic cement is Portland cement.

14. The composite mix according to claim 11, further comprising quartz sands of particle size of 0.25 to 4 mm and/or microsilica of particle size 0.1 to 0.4 microns.

15. The composite mix according to claim 11, wherein the base component is polyurethane.

16. The composite mix according to claim 11, further comprising fibers.

17. The composite mix according to claim 11, wherein the fibers are glass, polymer, steel, carbon, or cellulose containing fibers.
