A study on the synthesis of fly ash-based lightweight aggregate geopolymer concrete
(American Scientific Publishers All rights reserved., 2013-01)
The experiments conducting for current investigation aimed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) and explore the significance and limitations of the activator content on the ...
Fire resistance evaluation of lightweight geopolymer concrete system exposed to elevated temperatures of 100-800 °C
(Trans Tech Publications, 2014)
This paper reports the fire resistance property of a lightweight aggregate geopolymer concrete (LWAGC) material synthesized by the alkali-activation of locally source fly ash (FA) after exposed to elevated temperatures ...
Properties of metakaolin geopolymeric binder
(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 ...
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 ...
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 ...
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 ...
Physicochemical properties of pyrolitic carbon black from waste tyres
(Trans Tech Publications, 2014)
Waste tyres which are mainly generated from automotive industries have become a major environmental problem to the local authorities, the tyre industries and tyre dealer. When tyres are no longer usable due to worn-out, ...
