The objective of this research is to investigate the potential of geopolymers produced from fly ash, metakaolin and clay as high quality refractory. Geopolymers were synthesized through alkaline activation method and cured at 70°hour. The samples were subjected to various characterizations such as compressive and flexural strength, fire resistance and shock thermal measurements. Geopolymers made from fly ash showed higher compressive strength compared to those made from metakaolin and local clay. Fire resistance and thermal shock measurements indicated that the refractory quality of geopolymers made from fly ash, metakaolin, and local clay was very much the same. © 2016 Trans Tech Publications, Switzerland.
