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.
