Abstract: In the present studies, three different compositions of geopolymeric coating material have been developed utilizing fly ash, red mud, alkali activators and sodium dihydrogen phosphate. TiO2 and Fe2O3 nanoparticles are added to the developed coating material compositions as additives. These compositions are applied to mild steel plates by spray coating technique. Further, adhesive strength, water stability and anti-corrosion behavior of geopolymeric coated mild steel plates are determined. Developed geopolymeric coating material compositions are characterized for minerology, bonding behavior and morphology by XRD, FTIR and SEM respectively. Results revealed that among all the three coating material compositions, composition containing nano TiO2 exhibited best performance in terms of adhesive strength [3.1 MPa at 7th day], water resistance and corrosion resistance characteristics in 3.5 weight % sodium chloride solution by electrochemical measurements.
