Dry mix cement composition, methods and systems involving same
First Claim
1. A dry mix cement composition including an alkaline multi-phase aluminosilicate material, wherein the alkaline multi-phase aluminosilicate material provides a source of alkaline and soluble silicate to the cement composition, wherein the alkaline multi-phase aluminosilicate material is formed by activating an aluminosilicate material in the presence of an alkali material, wherein the alkali dosage is from 10-300% w/w of the aluminosilicate material to be activated, and wherein an oxidant is used during the activation.
