Abstract

The invention comprises a method comprising heating a solid, naturally occurring mineral so that at least a portion of the solid naturally occurring mineral melts to form an at least partially molten naturally occurring mineral and quenching the at least partially molten naturally occurring mineral in water so that at least a portion of the quenched naturally occurring mineral is in amorphous form.

First claim

What is claimed is:

1 . A method comprising:
heating a solid, naturally occurring mineral so that at least a portion of the solid naturally occurring mineral melts to form an at least partially molten naturally occurring mineral; and quenching the at least partially molten naturally occurring mineral in water so that at least a portion of the quenched naturally occurring mineral is in amorphous form.

2 . The method of claim 1 , wherein the quenched naturally occurring mineral comprises approximately 10% to approximately 99% by weight amorphous form.

3 . The method of claim 2 , wherein the quenched naturally occurring mineral is at least partially hyaloclastite.

4 . The method of claim 3 further comprising grinding the quenched naturally occurring mineral to a powder having volume-based mean particle size of less than or equal to 40 μm.

5 . The method of claim 4 further comprising combining the powder with portland cement, aggregate, and water.

6 . The method of claim 1 , wherein the naturally occurring mineral is basalt, intermediate, andesite, dacite, rhyolite or combinations or mixtures thereof.

7 . The method of claim 1 , wherein the naturally occurring mineral is olivine, pyroxene, amphibole, biotite, plagioclase, orthoclase, muscovite, quartz or combinations or mixtures thereof.

8 . A product made by the method of claim 1 .

9 . The product of claim 8 further comprising a hydraulic cement.

10 . The product of claim 9 , wherein the hydraulic cement is portland cement.

11 . The product of claim 10 further comprising aggregate and water to hydrate the portland cement.
