Performance of heat and ambient cured geopolymer concrete exposed to elevated temperatures
  J. Venkateswara Rao, K. Srinivasa Rao and K. Rambabu
  This paper presents an experimental study on fly ash based geopolymers cured under heat regime at 60oC for a period of 48 hours and their composites with a replacement of 20% of fly ash by ground granulated blast furnace slag, which are cured at ambient temperature. At the age of 28 days and 90 days, specimens are heated up to 800oC for 3 hours duration. Glass fibers are incorporated in geopolymers and their composites to study their influence on the residual mechanical properties due to thermal changes. Geopolymer composites exhibited better performance compared to geopolymer specimens with and without fibers.
