The term geopolymer is used for Alumino-silicate polymers formed in an alkaline environment [13]. During the process of geopolymerization, alumino-silicates are dissolved into alkali solution to form free SiO4 and AlO4 tetrahedral units. Further these SiO4 and AlO4 tetrahedrons linked alternatively where charge-balancing cations are provided by alkali metal cations and yield polymeric precursors
