A method for the manufacture of a high alumina hydraulic binder comprising hydrating a source of aluminium ions with a source of calcium ions in the presence of water to form mineral hydrates and subsequently heating said mineral hydrates to form said high alumina hydraulic binder.

A rapidly-expanding and -curing geopolymer formulation includes a liquid aqueous phase with silicate, aluminate and/or silico-aluminate precursors, an inorganic base, a monosaccharide and/or disaccharide, and a water-soluble peroxy compound. The saccharide and peroxy compound react spontaneously and rapidly in strongly alkaline conditions, producing an expanding gas and exothermic heat of reaction that drives at least an initial cure of the geopolymer formulation. The resulting foamed geopolymer formulation can be used in a variety of building and construction applications, as well as and others.
