Geopolymer is a new sustainable building material, developed to reduce CO2 foot print of existing cementing material. The material offers mechanical properties comparable to Ordinary Portland cements. Advantages associated with this material include thermal stability, acid resistance, compact structure, low density and ability to encapsulate hazardous wastes.Mainly composed of waste ashes and land fill material, this material shows multiple level of sustainability. Although, most of the research is focused in the field of construction industry, there is other utilization of this material. Catalysis, coating, encapsulation of hazardous waste and separation are some of the other applications. This review discusses a brief introduction geopolymer, its history and utilization in various fields. Goals for future research are also included as part of this review.

Geopolymer is a green and sustainable material synthesized by alkali activation of raw aluminosilicate rich materials. In this study class F-fly ash based sodium silicate free geopolymers were synthesized and used for coating application at 60OC. Setting time and adhesion strength analysis was performed using Vicat needle and Elcometer 108 according to ASTM C 807-08 and D 4541 respectively. Adhesion strength was found to enhance with increase in Na/Al ratio from 0.6 to 1.0 whereas no further increase was found for further increase in Na/Al molar ratio. A maximum of 3.8 MPa adhesion strength was produced by geopolymer with Na/Al=1 and water/solid = 0.33. Final setting time shown variation with varying Na/Al and water/solid ratios. It was found that geopolymers gained maximum strength within first 3 days and only partial changes has been noted in terms of adhesion strength in some samples. Infra Red spectroscopy was used as tool to understand the degree of geopolymerisation by observing the vibration frequency of -Si-O-T bonds around 1000 cm-1. X-ray fluorescence (XRF) was used to determine composition of Fly ash, whereas x-rays diffractometery (XRD) and scanning electron microscopy of the final product revealed the formation of geopolymer occurred without addition of sodium silicate. It can be concluded that sodium silicate free geopolymer has the potential to be used as a sustainable and green coating material for metals protection.
