Rice Hus. As. (RHA) Concrete is.an eco friendly concrete and has.ev.lv.d as.an innov.tiv. technology, capable of achiev.ng the s.atus.of being an outs.anding adv.ncement in the s.here of concrete technology. The utilization of Rice Hus. As. (RHA) will reduce the dumping of rice hus. as.well as.reduce the cons.ruction cos.. In this.communication inv.s.igations.for the determination of res.dual compres.iv. s.rength of M30 & 40 grades.of RHA concretes.expos.d at different temperatures.were carried. Almos. all s.ecimens.of M30 & 40 grades.of RHA concrete and normal concrete exhibited zero s.rength at a temperature of 1000°C. It s.ows.that concrete cannot withs.and a temperature of 1000°C and abov.. It was.als. concluded that compres.iv. s.rength of RHA concrete was.higher at °emperature below 500°C and decreas.s.abov. 500°C.
