Optimum mix design of geopolymers can be applied for application, such as lightweight concrete. In order to determine the maximum compressive strength for lightweight concrete production, fly ash geopolymers were produced with various ratios of fly ash/alkaline activator (0.5 - 3.0), Na2SiO3 solution/ NaOH solution (0.5 - 3.0) and 12 M of NaOH solution. The geopolymer materials were mixed and cured at 70°C for 24 h and tested on 7 days. Maximum compressive strength was obtained when the ratios of fly ash/alkaline activator and Na2SiO3solution/ NaOH solution were 2.0 and 2.5, respectively. The characterization and morphology of geopolymers were performed by using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). It was clearly shown that the best mix design ofgeopolymers produced denser matrix and less unreacted fly ash compared to other samples. 2014-03-19T04:12:09Z 2014-03-19T04:12:09Z 2013-04 Article Revista de Chimie, vol. 64(4), 2013, pages 382-387 0034-7752 http://www.revistadechimie.ro/article_eng.asp?ID=3648 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32852 en Institute for Scientific Information (ISI) |
