The sodium hydroxide and sodium silicate were mixed together to form an alkaline activator. Three parameters including NaOH molarity, mix design (fly ash/alkaline activator ratio and Na 2SiO 3/NaOH ratio), and curing temperature were examined. The maximum strength of 71 MPa was obtained when the NaOH solution of 12M, fly ash/alkaline activator of 2.0, Na 2SiO 3/NaOH of 2.5 and curing temperature of 60°C were used at 7 th days of testing. The results of SEM indicated that for geopolymer with highest strength, the structure was dense matrix and contains less unreacted fly ash with alkaline activator. 2013-08-14T13:30:06Z 2013-08-14T13:30:06Z 2012 Article Advanced Materials Research, vol. 476-478, 2012, pages 2173-2180 978-303785371-9 1022-6680 http://www.scientific.net/AMR.476-478.2173 http://hdl.handle.net/123456789/27444 en Trans Tech Publications |
