Effect of curing regimes on metakaolin geopolymer pastes produced from geopolymer powder
(Scientific.Net/Trans Tech Publications, 2012-12)
The properties of metakaolin geopolymer paste are affected by the alkali concentration, the initial raw materials, solidification process, and amount of mixing water as well as the curing conditions. This study aimed to ...
Strength and microstructural properties of mechanically-activated kaolin geopolymers
(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 ...
Properties of natural rubber/ethylene propylene diene monomer/recycled latex catheter (NR/EPDM/rLC) ternary blends: Cure characteristics and hardness
(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 ...
Study on solids-to-liquid and alkaline activator ratios on kaolin-based geopolymers
(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 ...
Effect of mechanical activation on kaolin-based geopolymers
(Trans Tech Publications, 2012)
Raw materials kaolin was subjected to mechanical modification; the effect of the mechanical activation of kaolin on the compressive strength and morphological properties of the geopolymers has been studied. Mechanical ...
Curing Behavior on kaolin-based geopolymers
(Trans Tech Publications, Switzerland., 2012)
This paper aims at investigating the influence of curing process on kaolin-based geopolymers. Kaolin-based geopolymers were prepared by the alkali-activation of kaolin with alkali activating solution (mixture of NaOH and ...
Ultra-violet radiation-cured biofiber composites from kenaf: The effect of montmorillonite on the flexural and impact properties
(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
(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 ...
