However, there are salient parameters that affecting the compressive strength of geopolymer. In this research, the effects of various NaOH molarities, Na 2SiO3/NaOH ratios, fly ash/alkaline activator, and curing temperature to the strength of geopolymer paste fly ash were studied. Tests were carried out on 50 x 50 x 50 mm cube geopolymer specimens. Compression tests were conducted on the seventh day of testing for all samples. The test results revealed that a 12 M NaOH solution produced the highest compressive strength for the geopolymer. The combination mass ratios of fly ash/alkaline activator and Na2SiO3/NaOH of 2.0 and 2.5, respectively, produced the highest compressive strength after seven days. Geopolymer samples cured at 60 °C produced compressive strength as high as 70 MPa. 2016-06-25T01:53:26Z 2016-06-25T01:53:26Z 2011 Article Advanced Materials Research, vol.328-330, 2011, pages 1475-1482 1022-6680 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/42189 10.4028/www.scientific.net/AMR.328-330.1475 en Trans Tech Publications
