Abstract

The invention comprises a composition comprising hyaloclastite having 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 hyaloclastite, wherein the hyaloclastite 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 hyaloclastite, wherein the hyaloclastite 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

1 - 41 . (canceled)

43 . The composition of claim 42 , wherein the mineral comprises approximately 15% to approximately 95% by weight amorphous form.

44 . The composition of claim 42 , wherein the mineral comprises approximately 15% to approximately 90% by weight amorphous form.

45 . The composition of claim 42 , wherein the mineral comprises approximately 5% to approximately 20% by weight Al 2 O 3 .

46 . The composition of claim 42 , wherein the mineral is basaltic or intermediate.

47 . The composition of claim 42 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 20 μm.

48 . The composition of claim 42 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 10 μm.

49 . A mixture comprising:
a mineral formed from molten lava or magma 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 and wherein the mineral has a volume-based mean particle size of less than or equal to approximately 40 μm; and a hydraulic cement.

50 . The mixture of claim 49 , wherein the mineral comprises approximately 15% to approximately 95% by weight amorphous form.

51 . The mixture of claim 49 , wherein the mineral comprises approximately 15% to approximately 90% by weight amorphous form.

52 . The mixture of claim 49 , wherein the mineral comprises approximately 5% to approximately 20% by weight Al 2 O 3 .

53 . The mixture of claim 49 , wherein the mineral is basaltic or intermediate.

54 . The mixture of claim 49 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 20 μm.

55 . The mixture of claim 49 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 10 μm.

56 . A mixture comprising:
a mineral formed from molten lava or magma 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 and wherein the mineral has a volume-based mean particle size of less than or equal to approximately 40 μm; aggregate; a hydraulic cement; and water sufficient to hydrate the hydraulic cement.

57 . The mixture of claim 56 , wherein the mineral comprises approximately 15% to approximately 95% by weight amorphous form.

58 . The mixture of claim 56 , wherein the mineral comprises approximately 15% to approximately 90% by weight amorphous form.

59 . The mixture of claim 56 , wherein the mineral comprises approximately 5% to approximately 20% by weight Al 2 O 3 .

60 . The mixture of claim 56 , wherein the mineral is basaltic or intermediate.

61 . The mixture of claim 56 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 20 μm.

62 . The mixture of claim 56 , wherein the mineral has a volume-based mean particle size of less than or equal to approximately 10 μm.
