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 ...
Potential application of palm ash as a raw materials in production of green glass
(Scientific.Net/Trans Tech Publications, 2012-12)
Oil Palm Ash is one of the abundance agricultural wastes found in Malaysia. This wastes need to be disposed properly. Oil palm ash contains compounds needed to produce glass. Most of raw materials (especially silica) used ...
Halal based sourced EM for turbidity reducing in wastewater treatment
(Trans Tech Publications, 2014)
Effective Microorganism (EM) technology was found as the credible solution to solve many environmental problems including wastewater issues. The EM which is in the form of EM mud ball was tested to be effectively used for ...
Kaolin-based geopolymers with various NaOH concentrations
(Springer Verlag, 2013-03)
Kaolin geopolymers were produced by the alkali-activation of kaolin with an activator solution (a mixture of NaOH and sodium silicate solutions). The NaOH solution was prepared at a concentration of 6-14 mol/L and was mixed ...
Influence of oxide molar ratios on kaolin geopolymers
(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 ...
Study on fly ash based geopolymer for coating applications
(Trans Tech Publications, 2013)
Geopolymer is cementitious binders that do not require the presence of ordinary Portland cement (OPC). Fly ash with geopolymer formulations prepared with mixing alumino-silicate with the alkaline activator solution has ...
Mechanical properties of polymer composites with sugarcane bagasse filler
(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
(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 ...
Effect of fly ash/alkaline activator ratio and sodium silicate/NaoH ratio on fly ash geopolymer coating strength
(Trans Tech Publications, 2013)
Fly ash geopolymer coating material potential used to protect surface used in exposure conditions. Ratio of fly ash/alkaline activator and Na₂SiO₃/NaOH play important parameter on determining the best flexural strength of ...
