Geopolymer Composition, A Method For Preparing the Same and Its Uses

Abstract

A geopolymer composition for use as a cement or concrete is provided, the composition comprising: (a) fly ash (FA); (b) ground granulated blast-furnace slag (GGBS); and (c) high-magnesium nickel slag (HMNS). The composition may optionally comprise a filler. A method for forming a geopolymer composition is also provided, the method comprising: providing a geopolymer precursor comprising: (a) fly ash (FA); (b) ground granulated blast-furnace slag (GGBS); and (c) high-magnesium nickel slag (HMNS); combining components (a) to (c) with an activator, the activator comprising a silicate and a base in solution in a solvent; and allowing the resulting mixture to cure. The geopolymer composition advantageously comprises one or more allotropes of carbon, in particular a carbon nano-structure material, for example nanotubes, nanobuds and nanoribbons. The geopolymer composition finds use in form a wide range of construction components and structures.
