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 ...
Mechanical performances of fly ash geopolymer bricks
(American Scientific Publishers, 2013-01)
Geopolymer is a new class of three-dimensionally networked amorphous to semi-crystalline alumino-silicate materials, and first developed by Professor Davidovits in 1978. Geopolymers can be synthesized by mixing alumino-silicate ...
Lightweight fly ash-based geopolymer concrete
(Trans Tech Publications, 2013)
The experiments of this study were preformed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) using normal sand as a fine aggregate and expanded clay as lightweight aggregate. The LWAGC ...
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 ...
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 ...
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 ...
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 ...
Processing and characterization of calcined kaolin cement powder
(Elsevier Ltd, 2012-05)
Abstract
This paper aimed at investigating the possibility of calcined kaolin to produce cement powder that could be an alternative to Portland cement by applying geopolymerization process. Cement paste was firstly made ...
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 ...
