NOVELTY - A cementless binder composition comprises a reaction product of a mixture comprising fly ash, calcium oxide, nanosilica, water, an effective amount of an activator to activate the mixture, graphene and/or calcined coke. USE - Binder composition used for structural purposes and non-load bearing construction materials such as concrete production, fly-ash pellets, embankments and other structural fills for road/wall construction, grout and flowable fill production, waste stabilization and solidification, mine reclamation, stabilization of soft soils, road sub-base construction, road/highway pavements, aggregate substitute material, brick production, mineral filler in asphaltic concrete, agricultural use, soil stabilization in stock feed yards, agricultural stakes, loose application on rivers to melt ice, loose application on roads and parking lots for ice control (all claimed). ADVANTAGE - The binder composition is inexpensive, environmentally-friendly, and has excellent compressive strength.
