      Cheng, Yong Heah; Hazlinda, Kamarudin; Mohd Mustafa Al-Bakri, Abdullah; Luqman, Musa, Dr.; Khairul Nizar, Ismail, Assoc. Prof. Dr; Liew, Y. M. (INSInet Publications, 2011-07)
      Kaolin is a white raw material that has an essential constituent which makes it ideal for industrial applications such as green concrete. Based on a historical review, it appears that green polymeric composites created by ...

    • Processing and characterization of calcined kaolin cement powder 

      Liew, Yun Ming; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Mohd Mustafa Al Bakri, Abdullah; Luqman, Musa, Dr.; Khairul Nizar, Ismail, Assoc. Prof. Dr.; Che Mohd Ruzaidi, Ghazali; Cheng, Yong Heah (Elsevier Ltd, 2012-05)
      Abstract This paper aimed at investigating the possibility of calcined kaolin to produce cement powder that could be an alternative to Portland cement by applying geopolymerization process. Cement paste was firstly made ...

    • Properties of metakaolin geopolymeric binder 

      Liew, Yun Ming; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Mohd Mustafa Al Bakri, Abdullah; Mohamed, Bnhussain, Prof. Dr.; Luqman, Musa, Dr.; Khairul Nizar, Ismail, Assoc. Prof. Dr.; Che Mohd Ruzaidi, Ghazali, Prof. Madya; Heah, Cheng Yong (American Scientific Publishers, 2013-01)
      This paper investigates the physical and mechanical properties as well as the morphology study of the MK geopolymeric binder. Mixture of waterglass liquid and NaOH solution were used as the activator solution for the ...

      Lokman Hakim, Ibrahim; Nik Noriman, Zulkepli, Dr.; Sam, Sung Ting, Dr.; Luqman, Musa; Rosniza, Hamzah (Trans Tech Publications, 2013-12)
      Currently, the recycled rubber widely being used in rubber technology. Due to difficulty on reprocessing techniques, the vulcanized rubbers being a big problem in the recycled field. One of the main forms of discharge ...

    • Strength and microstructural properties of mechanically-activated kaolin geopolymers 

      Cheng, Yong Heah; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Mohd Mustafa Al Bakri, Abdullah; Mohammed, Bnhussain; Luqman, Musa; Khairul Nizar, Ismail; Che Mohd Ruzaidi, Ghazali, Prof. Madya; Liew, Yun Ming (Trans Tech Publications, 2012-12)
      Kaolin geopolymers exhibit low strength properties due to its plate-like nature which contribute to smaller surface area for geopolymerization reactions. Layered kaolin structure only allows very little, if any, substitution ...

    • 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 ...

    • Tensile properties of kenaf/unsaturated polyester composites filled with a montmorillonite filler 

      Rozman, Haji Din, Prof.; Luqman, Musa, Dr.; Azniwati, A. A.; Rozyanty, Abdul Rahman (Wiley Periodicals, Inc., 2011-03-05)
      Kenaf/unsaturated polyester composites filled with montmorillonite (MMT) filler were produced. Overall, the study showed that, for samples with kenaf filler only, the strength properties decreased as the kenaf filler loading ...
