Abstract

Provided herein are methods and compositions utilizing one or more cementitious replacement materials, one or more alkaline activating materials, and, optionally one or more bonding materials and/or one or more setting time enhancer materials. The one or more cement precursors comprise - one or more of aluminosilicates, siloxo-aluminates, poly(Siloxo)/poly(siloxonate)/poly (silanol), poly (ferro-sialate), ortho silicate, ortho (siloxonate), oligo silicates, hydrosodalite, silonate, phosphate based material or - one or more cement precursors comprise lagoon ash, basic oxygen slag (BOS), electric arc furnace (EAF) slag, mill scale, desulferization slag, black/white slag, fly ashes, blast furnace flue dust, red mud, and/or iron ore agglomerate. The one or more alkaline activating agents comprises potassium silicate, potassium hydroxide, sodium hydroxide, sodium silicate, calcium hydroxide, magnesium hydroxide, reactive magnesium oxide, calcium chloride, sodium carbonate, silicone dioxide, sodium aluminate, calcium sulfate, sodium sulfate, or dolomite, or a combination thereof. Further disclosed is a method and a system comprising a vertical impact mill.
