Abstract
Official abstract text for this publication.
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 - 20 . (canceled) 21 . A cementitious material comprising: hyaloclastite having a volume-based mean particle size of less than or equal to approximately 40 μm; and a mineral or compound having reactive hydroxyl groups. 22 . The cementitious material of claim 21 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 20 μm. 23 . The cementitious material of claim 21 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 10 μm. 24 . The cementitious material of claim 21 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 5 μm. 25 . The cementitious material of claim 21 , wherein the mineral or compound having reactive hydroxyl groups is CaOH. 26 . The cementitious material of claim 25 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 20 μm. 27 . The cementitious material of claim 25 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 10 μm. 28 . The cementitious material of claim 25 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 5 μm. 29 . The cementitious material of claim 21 , wherein the mineral or compound having reactive hydroxyl groups CaO and water. 30 . The cementitious material of claim 21 further comprising water. 31 . A cementitious-based material comprising: aggregate; hyaloclastite having a volume-based mean particle size of less than or equal to approximately 40 μm; a mineral or compound having reactive hydroxyl groups; and water. 32 . The cementitious-based material of claim 31 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 20 μm. 33 . The cementitious-based material of claim 31 , wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 10 μm. 34 .
