      This paper reported the properties of kaolin geopolymers in term of the bulk density, compressive strength, qualitative observation and SEM analysis of the kaolin geopolymers. Kaolin geopolymers were synthesized through ...

    • Influence of oxide molar ratios on kaolin geopolymers 

      Heah, Cheng Yong; 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; Liew, Yun Ming (American Scientific Publishers, 2013-12)
      Oxide molar ratios are the main key parameter determining the performance of a kaolin geopolymers. The kaolin composition and various mixture proportions will lead to different oxide molar ratios in geopolymer system. In ...

    • Malaysian Foxtail grass - A potential source of natural/agro fibre for polymer composite panel 

      Che Mohd Ruzaidi, Ghazali, Prof. Madya; Mohd Mustafa Al Bakri, Abdullah; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Norazian, Mohamed Noor; Rafiza, Abdul Razak; Zarina, Yahya (Trans Tech Publications, 2013)
      Foxtail grass, also known as 'rumput bulu' by the local people, is one of the fast growing grasses abundantly available all over Malaysia. A full grown Foxtail grass attains a height of about 0.5 - 1.5 meters. The fibres ...

    • Mechanical properties of polymer composites with sugarcane bagasse filler 

      Mohd Mustafa Al-Bakri, Abdullah; Liyana, Jamaludin; Norazian, Mohamed Noor; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Che Mohd Ruzaidi, Ghazali, Prof. Madya (Trans Tech Publications, 2013)
      Natural fibers reinforced polymer composites have gained more interest because of their biodegradable, light weight, less expensive sources, easy processing, high specific modulus and also environmentally friendly appeal. ...

    • Optimization of alkaline activator / fly ash ratio on the compressive strength of manufacturing fly ash-based geopolymer 

      Mohd Mustafa Al Bakri, Abdullah; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; O. A. K. A., Karem; Che Mohd Ruzaidi, Ghazali, Prof. Madya; Rafizah, Abu Rashid; Norazian, Mohamed Noor (Trans Tech Publications, 2012)
      Fly ash and a mixture of alkaline activators namely sodium silicate (Waterglass) and sodium hydroxide (NaOH) solution were used for preparing geopolymer. The aim of this research is to determine the optimum value of the ...
