Eight rice husk ashes with different grinding time, i.e. coarse original rice husk ash (RHA0), RHA1, RHA2, RHA3, RHA4, RHA5, RHA6, and RHA7 were used for the study. The TGA/ DTA analysis and X-ray fluorescence (XRF) was used through this investigation. On the other hand, the pozzolanic activity index of the RHA was assessed in accordance with ASTM C 311-11a. From the experiment, it was found that the greater the weight loss, the less the crystallinity of the RHA. In addition, there are no significant differences in chemical compositions of the rice husk ashes with different grinding time. Furthermore, when the grinding time increased from 1 hour and 30 minutes to 5 hours, there was a significant drop in the pozzolanic index. 2016-05-06T08:13:29Z 2016-05-06T08:13:29Z 2012 Article Procedia Engineering, vol. 50, 2012, pages 101-109 1877-7058 http://www.journals.elsevier.com/procedia-engineering/ http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41472 en Elsevier B.V.
