The role of alkaline activator in geopolymer is important for its mechanical properties. NaOH and sodium silicate solution was used as alkaline activator. In order to investigate effect of NaOH concentration on microstructure of boiler ash based geopolymer 6 different NaOH concentration (6M, 8M, 10M, 12M, 14M, 16M) were used. The boiler ash based geopolymer samples were cured in oven at temperature 80 °C for 24 hr. The compressive strength of geopolymer samples at 7 days showed that 14M obtained the maximum strength (13. 9 MPa). This result was supported with SEM analysis were the 14M geopolymer sample showed more dense geopolymer matrix compared to others. 2016-05-06T09:42:08Z 2016-05-06T09:42:08Z 2015 Article Materials Science Forum, vol.803, 2015, pages 173-178 1662-9752 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41479 10.4028/www.scientific.net/MSF.803.173 en Trans Tech Publications Ltd. |
