Low calcium alkali-activated binders (also know as geopolymers), a class of inorganic polymers having an amorphous structure consisting of [SiO4]4− and [AlO4]5− tetrahedrals which share all of their corners with each other through oxygen atoms, are generally produced through the reaction of 'an aluminosilicate normally supplied in powder form as an industrial by-product or other inexpensive material with an alkaline activator, which is usually a concentrated aqueous solution of alkali hydroxide, silicate, carbonate or sulphate’.
On account of their reduced carbon dioxide emissions during production, geopolymers are one of the primary replacements for ordinary Portland cement (OPC), whose production requires large amounts of energy and emits much anthropogenic CO2
