    • Correlation of microstructure and flexural strength of fly ash geopolymer of varying molarities 

      Yong-Sing, Ng; Yun-Ming, Liew; Cheng-Yong, Heah; Mohd Mustafa Al Bakri, Abdullah; Hui-Teng, Ng; Amir, Naveed (IOP Publishing Ltd, 2019-08)
      The present work studies and compares the flexural properties of fly ash geopolymer with varying molarity of sodium hydroxide (NaOH). Different molarities of NaOH solution (6M, 8M, 10M, 12M and 14M) are used to prepare the ...

    • Effect of solid-to-liquid ratio on thin fly ash geopolymer 

      Yong-Sing, Ng; Yun-Ming, Liew; Mohd Mustafa Al Bakri, Abdullah; Hui-Teng, Ng; Kamarudin, Hussin; Cheng Yong, Heah; Nurul Aida, Mohd Mortar; Sandu, Andrei Victor (IOP Publishing Ltd, 2020-02)
      The present work studies the effect of solid-to-liquid (S/L) ratio on the properties of thin fly ash-based geopolymer. The fly ash geopolymers with dimension of 160 mm × 40 mm × 10 mm were synthesised by using various S/L ...

    • Microstructural analysis of fly ash-based geopolymers with various alkali concentration 

      Hui-Teng, Ng; Cheng-Yong, Heah; Yun-Ming, Liew; Mohd Mustafa Al Bakri, Abdullah; Yong-Sing, Ng (IOP Publishing Ltd, 2019-08)
      In the present work, a comparative study on the effect of different concentration of sodium hydroxide (NaOH) on fly ash-based geopolymer was investigated. The geopolymer synthesis by mixing fly ash with alkali activator ...
