    • 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 ...

    • Properties of natural rubber/ethylene propylene diene monomer/recycled latex catheter (NR/EPDM/rLC) ternary blends: Cure characteristics and hardness 

      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 ...

    • Ultra-violet radiation-cured biofiber composites from kenaf: The effect of montmorillonite on the flexural and impact properties 

      Rozman, H. D.; Rozyanty, Abdul Rahman; Luqman, Musa; G. S. Tay (Taylor & Francis, 2010-04)
      Biofiber composites, cured by ultra-violet (UV) radiation were produced using kenaf fibers as the reinforcing agent and unsaturated polyester as the matrix. This research work focused on the effects of the incorporation ...

    • Unsaturated polyester-kenaf composites: The effects of a modified montmorillonite filler on the tensile properties 

      R. H., Din; Luqman, Musa; A. A., Musa; Tay, G. -S. (Taylor & Francis Group, LLC., 2010-06)
      This study has been embarked to use the nanofiller to compensate the adverse effect of the lignocellulosic filler. Unsaturated polyester-kenaf composites filled with various types of MMT filler were produced. The study ...
