Rice husk is an agro waste material which is produced in about 300 million metric tons in worldwide annually. Approximately, 100 Kg of rice husk are obtained from 500 Kg of rice. Rice husks contain organic substances and 20% of inorganicmaterial.Ricehuskash(RHA)isobtainedbythecombustionofricehusk.Theburningtemperaturemustbewithin therangeof600to8000C.Theashobtainedhastobegroundedinaballmillfor30minutesanditsappearanceincolourwill begrey.ThemostimportantpropertyofRHAthatdeterminespozzolanicactivityistheamorphousphasecontent.RHAisa highlyreactivepozzolanicmaterialsuitableforuseinlime pozzolanamixesandforPortlandcementreplacement.
