Influence of activator composition on the properties of calcined kaolin geopolymeric powder
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
This paper studied the influence of activator composition on the properties of calcined kaolin geopolymeric powder. The alkaline activation of calcined kaolin was performed in mixture of waterglass liquid and NaOH solution ...
Effect of curing regimes on metakaolin geopolymer pastes produced from geopolymer powder
(Scientific.Net/Trans Tech Publications, 2012-12)
The properties of metakaolin geopolymer paste are affected by the alkali concentration, the initial raw materials, solidification process, and amount of mixing water as well as the curing conditions. This study aimed to ...
The processing, characterization, and properties of fly ash based geopolymer concrete
(Advanced Study Center Co. Ltd, 2012)
In recent years, attempts to increase the utilization of fly ash as a replacement for ordinary Portland cement (OPC) in concrete have increased in significance. Geopolymer concrete does not need the presence of Portland ...
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 ...
The effect of curing time on the properties of fly ash-based geopolymer bricks
(Scientific.Net/Trans Tech Publications, 2012-12)
This paper reports the results of an experimental work conducted to investigate the effect of curing conditions on the properties of fly ash-based geopolymer bricks prepared by using fly ash as base material and combination ...
The influence of curing periods on the compressive strength of fly ash-based geopolymer at different aging times
(Trans Tech Publications, 2012)
The results of the current experimental investigation indicate the significant effect of the heating periods on the compressive strength of fly ash-based geopolymers prepared at different alkaline liquid content at both ...
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 ...
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 ...
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 ...
