Studies on fly ash based geopolymeric material for coating on mild steel by paint brush technique

The present work focuses on the study of five different compositions of fly ash based geopolymeric material with varying silicate: alkali ratio as coating material on mild steel plates. Coated mild steel plates were tested for adhesion strength, heat resistance, fire resistance, water absorption and corrosion resistance characteristics. Mineralogy, morphology and vibrations of various functional groups present in the developed coating material compositions were evaluated by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) and Fourier transform infra-red spectral studies (FTIR) respectively. The developed coating material possesses promising fire resistance, heat resistance, corrosion resistance characteristics and mechanical properties.
