Abstract

The invention comprises a composition comprising a natural pozzolan selected from hyaloclastite, sideromelane or tachylite, wherein the natural pozzolan has a volume-based mean particle size of less than or equal to 40 μm. The invention also comprises a cementitious material comprising a hydraulic cement and a natural pozzolan selected from hyaloclastite, sideromelane, tachylite or combination or mixtures thereof, wherein the natural pozzolan has a volume-based mean particle size of less than or equal to approximately 40 μm. The invention further comprises a cementitious-based material comprising aggregate, a cementitious material comprising a hydraulic cement and a natural pozzolan selected from hyaloclastite, sideromelane, tachylite or combination or mixtures thereof, wherein the natural pozzolan has a volume-based mean particle size of less than or equal to approximately 40 μm and water sufficient to hydrate the cementitious material. A method of using the composition of the present invention is also disclosed.

First claim

What is claimed is:

1. A mixture comprising:
a composition formed from a molten mineral that has been quenched by water to form a fragmented, solid mineral, wherein the mineral comprises approximately 43% to approximately 57% by weight SiO 2 , wherein the mineral comprises approximately 10% to 99% by weight amorphous form, wherein the mineral is reduced in size to a plurality of particles having a volume-based mean particle size of less than or equal to approximately 40 μm and wherein the plurality of particles have pozzolanic properties; and
a hydraulic cement.

2. The mixture of claim 1 , wherein the mineral comprises approximately 15% to approximately 95% by weight amorphous form.

3. The mixture of claim 1 , wherein the mineral comprises approximately 50% to approximately 95% by weight amorphous form.

4. The mixture of claim 1 , wherein the mineral is basaltic.

5. The mixture of claim 1 , wherein the mineral is intermediate.

6. The mixture of claim 1 , wherein the mineral comprises approximately 43% to approximately 53% by weight SiO 2 .

7. The mixture of claim 1 , wherein the mineral comprises approximately 53% to approximately 57% by weight SiO 2 .

8. The mixture of claim 1 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 20 μm.

9. The mixture of claim 1 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 10 μm.

10. The mixture of claim 1 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 5 μm.

11. The mixture of claim 10 , wherein the mineral comprises approximately 50% to approximately 95% by weight amorphous form.

12. The mixture of claim 11 further comprising aggregate and water sufficient to hydrate the hydraulic cement.
