Geopolymer is a term covering a class of synthetic aluminosilicate materials with potential use in a number of areas, essentially as a replacement for Portland cement and for advanced high-tech composites, ceramic applications or as a form of cast stone.
Geopolymer binders and geopolymer cements are generally formed by reaction of an aluminosilicate powder with an alkaline silicate solution at roughly ambient conditions.
Geopolymer cements can also be made from sources of pozzolanic materials, such as lava or fly ash from coal.
Geopolymer concrete based on pozzolana is a new material that does not need the presence of Portland cement as a binder.
