Fly ash porous material using geopolymerization process for high temperature exposure
(MDPI AG (Basel, Switzerland), 2012-04)
This paper presents the results of a study on the effect of temperature on geopolymers manufactured using pozzolanic materials (fly ash). In this paper, we report on our investigation of the performance of porous geopolymers ...
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 ...
Potential of marine clay as raw material in geopolymer composite
(Scientific.Net/Trans Tech Publications, 2012-12)
In this research, marine clays has been studied its potential as a matrix composite materials that tend to be used as alternative materials to concrete. The study shows that marine clays which mixed with appropriate ...
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 ...
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 ...
