The geopolymerisation process occurs due to the mixing of fly ash, sodium silicate and sodium hydroxide as the alkaline activator, which produces aluminosilicate gel that acts as a binder. As such, the ratios of fly ash to alkaline activator and Na 2SiO 3/NaOH play an important role in obtaining desirable compressive strength; the concentration of NaOH used in this study was 12 M. Different ratios of fly ash to alkaline activator (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0) and Na 2SiO 3/NaOH (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0) were investigated in order to determine the maximum compressive strength. The alkaline activator was mixed with fly ash with different ratio as mentioned above and the samples were cured at 70°C for 24 hours and tested on the seventh day. The maximum compressive strength was obtained when the ratios of fly ash to alkaline activator and Na 2SiO 3/NaOH were 2.0 and 2.5 with compressive strength 73.86 MPa. 2013-08-14T14:29:47Z 2013-08-14T14:29:47Z 2012 Article Advanced Materials Research, vol. 341-342, 2012, pages 189-193 1022-6680 978-303785371-9 http://www.scientific.net/AMR.341-342.189 http://hdl.handle.net/123456789/27445 en Trans Tech Publications |
