Description:Davidovits proposed that an alkaline liquid could be used to react with the silicon (Si) and the
aluminum (Al) in a source material of geological origin or in by-product materials such as fly ash and rice
husk ash to produce binders. Because the chemical reaction that takes place in this case is a
polymerization process, he coined the term ‘Geopolymer’ to represent these binders. Geopolymers are
members of the family of inorganic polymers. The chemical composition of the Geopolymer material is
similar to natural zeolitic materials, but the microstructure is amorphous. The polymerization process
involves a substantially fast chemical reaction under alkaline condition on SiAl minerals, that results in a
three-dimensional polymeric chain and ring structure consisting of Si-OAl-O bonds.Water expelled from
the Geopolymer matrix during the curing and further drying periods, leaves behind discontinuous Nanopores in the matrix, which provide benefits to the performance of Geopolymers. The water in a
Geopolymer mixture, therefore, plays no role in the chemical reaction that takes place; it merely provides
the workability to the mixture during handling. This is in contrast to the chemical reaction of water in a
Portland cement concrete mixture during the hydration process. There are two main constituents of
Geopolymers, namely the source materials and the alkaline liquids. The source materials for Geopolymers
based on alumina-silicate should be rich in silicon (Si) and aluminum (Al). These could be natural minerals
such as kaolinite, clays, etc. Alternatively, by-product materials such as fly ash, silica fume, slag, rice-husk
ash, red mud, etc. could be used as source materials. The choice of the source materials for making
Geopolymers depends on factors such as availability, cost, type of application, and specific demand of the
