Effect of alkali concentration on mechanical properties of kaolin geopolymers
(Foundation for Materials Science and Engineering, 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 ...
Influence of solids-to-liquid and activator ratios on calcined kaolin cement powder
(Elsevier BV, 2011)
This paper summarizes the effect of activator ratio on the processing of cement powder. Geopolymer slurry was produced via alkaline activation of calcined kaolin. Once the geopolymer slurry solidified, it was crushed and ...
Optimization of solids-to-liquid and alkali activator ratios of calcined kaolin geopolymeric powder
(Elsevier Ltd, 2012-12)
This paper investigates the effect of S/L and alkali activator ratios on the synthesis of geopolymeric powder. Geopolymeric powder was synthesized by applying geopolymerization process. By adopting the concept of "just ...
Calcined kaolin geopolymeric powder: Influence of water- to geopolymeric powder ratio
(Trans Tech Publications, 2012-07)
This paper describes the synthesis of calcined kaolin geopolymeric powder from the alkaline activation of calcined kaolin followed by solidification and pulverizing process. The geopolymeric powder was used by just adding ...
Influence of solidification process on calcined kaolin geopolymeric powder
(Trans Tech Publications, 2012-02)
This paper aims at investigating the influence of solidification condition on the processing of calcined kaolin geopolymeric powder. This is a new process developed using the geopolymerization process. Geopolymer slurry ...
Influence of solid-to-liquid ratio on properties of fly ash geopolymer ceramics
(IOP Publishing Ltd, 2019-08)
Ceramics has come to be progressively very important in industry because of their exceptional mechanical and physical properties The motivation to develop fly ash geopolymer ceramics was to overcome the problem associated ...
Investigation of heat released during geopolymerization with fly ash based geopolymer
(IOP Publishing Ltd, 2019-08)
Geopolymerization consists of several chemical reactions that has been reported widely as an exothermic reaction. Previous studies on heat released during geopolymerization used metakaolin and fly ash of F class as a ...
Porous metakaolin geopolymers with tailored thermal conductivity
(IOP Publishing Ltd, 2019-08)
In this work, a novel lightweight metakaolin geopolymers were produced by using hydrogen peroxide as foaming agent. The influence of the hydrogen peroxide incorporation content (0.25 – 1.25%) on density, compressive strength ...
Synthesis of sodium silicate from rice husk ash as an activator to produce epoxy-geopolymer cement
(IOP Publishing Ltd, 2021-03)
Rice husk ash (RHA), a byproduct of the rice industry, is the primary source of amorphous silica for producing sodium silicate solutions to replace standard commercial sodium silicate in geopolymer mixture design. The ...
