    • Influence of solids-to-liquid and activator ratios on calcined kaolin cement powder 

      Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Che Mohd Ruzaidi, Ghazali, Assoc. Prof.; Luqman, Musa, Dr.; Mohd Mustafa Al Bakri, Abdullah; Heah, Cheng Yong; Khairul Nizar, Ismail; Mohammed, Binhussain; Liew, YunMing (Elsevier BV, 2011)
      This paper summarizes the effect of activator ratio on the processing of cement powder. Geopolymer slurry was produced via alkaline activation of calcined kaolin. Once the geopolymer slurry solidified, it was crushed and ...

    • Study on solids-to-liquid and alkaline activator ratios on kaolin-based geopolymers 

      Cheng, Yong Heah; Kamarudin, Hussin, Brig. Gen. Dato' Prof. Dr.; Mohd Mustafa Al-Bakri, Abdullah; Mohammed, Hussain; Luqman, Musa; Khairul Nizar, Ismail, Assoc. Prof. Dr.; Che Mohd Ruzaidi, Ghazali; Liew, Yun Ming (Elsevier Ltd., 2012-10)
      Kaolin and alkali activator were mixed with the solids-to-liquid ratios in range of 0.60-1.20 (Al 2O 3/Na 2O molar ratio of 0.63-1.27). Sodium silicate and sodium hydroxide ranged between 0.16 and 0.36 (SiO 2/Na 2O molar ...
