Effect of alkali concentration on mechanical properties of kaolin geopolymers
(Procema SA, 2012)
Alkali concentration is the most significant factor in geopolymerization process that must be taken into consideration during the synthesis of kaolin geopolymers. The kaolin geopolymers were prepared by mixing kaolin and ...
Correlating composition design and properties of calcined kaolin geopolymeric powder
(American Scientific Publishers, 2013-12)
This paper discussed the relation between composition design and properties of calcined kaolin geopolymeric powder. Geopolymeric powder was produced by applying the geopolymerization process. The solids-to-liquid ratios ...
Effects of Acetic Anhydride on the properties of Polypropylene(PP)/Recycled Acrylonitrile Butadiene(NBRr)/Rice Husk Powder(RHP) composites
(Taylor and Francis Ltd., 2012-11)
PP/NBRr/RHP composites were prepared by incorporation of rice husk powder at different loadings into PP/NBRr matrix with an internal mixer at 180°C for 9 min and 50 rpm rotor speed. The effects of rice husk powder filler ...
Alteration in the microstructure of fly ash geopolymer upon exposure to elevated temperatures
(Trans Tech Publications, 2013)
This paper represents the mechanical and microstructure changes in geopolymeric material synthesized by the alkali activation of locally source fly ash at high temperatures of 400, 600 and 800 °C. The high compressive ...
Strength of concrete with ceramic waste and quarry dust as aggregates
(Trans Tech Publications, 2013)
This research focuses on a study of the strength of concrete with ceramic waste as coarse aggregate and quarry dust as fine aggregate. The sources of ceramic waste and quarry dust are obtained from the industrial in Malaysia. ...
Effect maleic anhydride polypropylene on properties of calcium carbonate filled polypropylene/ethylene propylene diene terpolymer composites
(Trans Tech Publications, 2014)
Inorganic filler, calcium carbonate (CaCO₃) was used as filler in the polypropylene (PP)/ ethylene propylene diene terpolymer (EPDM) composites. The composites were compatibilized with Maleic anhydride grafted polypropylene ...
Compressive strength and morphology of fly ash based geopolymer as artificial aggregate with different curing temperature
(Trans Tech Publications, 2014)
This paper presented the compressive strength of geopolymer paste with different NaOH concentration and morphology analysis for sintered artificial aggregate. This artificial aggregate was produce based on mix design with ...
Comparison of processing and mechanical properties of polypropylene/recycled acrylonitrile butadiene rubber/rice husk powder composites modified with silane and acetic anhydride compound
(SAGE Publications Ltd, 2014-12)
Polypropylene (PP)/recycled acrylonitrile butadiene rubber (NBRr)/rice husk powder (RHP) composites were fabricated with silane and acetic anhydride (Ac) treatment agent. The in situ formed RHP-filled PP/NBRr composites ...
Electronic structure, electronic charge density and optical properties of 3-methyl-1,4-dioxo-1, 4-dohydronaphthalen-2-yl-sulfanyl (C₁₃H₁₀O₄S)
(ESG, 2014)
The atomic positions of 3-methyl-1,4-dioxo-1, 4-dohydronaphthalen-2-yl-sulfanyl (3MDS) single crystal taken from XRD data were optimized by minimizing the forces. We make use of the optimized geometry as a starting point ...
Comparative study on thermal, compressive, and wear properties of palm slag brake pad composite with other fillers
(Trans Tech Publications, 2011)
The attractive performance-to-cost ratio associated with the incorporation of waste material in composite formulations used to produce brake pads has stimulated the idea of exploring the possible incorporation of additional ...
