Abstract

Geopolymerisation also known as alkali activation of aluminosilicate occurs when mineral sources with high Al and Si content such as kaolin, blast furnace slag or fly ash are exposed to high alkaline environments, thus producing two to three dimensional Si-O-Al structure which exhibits both zeolitic and ceramic properties which is not typically present in traditional cement materials such as ordinary Portland Cement (OPC). Kaolin based geopolymers, inorganic polymers that are also alumino-silicate materials with impressive mechanical properties such as excellent coating materialfor fire resistant, poor electric conductor, chemically unreactive over a wide range of pH, non-abrasive, low energy consumption, poor permeability and emits less CO2 which makes earth a better place. This paper is to review the progress made in kaolin based geopolymers that are currently in growing demand of researchers to replace existing eco-unfriendly materials.
