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 ...
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 ...
Microstructure study on optimization of high strength fly ash based geopolymer
(Trans Tech Publications, 2012)
The compressive strength and microstructural characteristics of fly ash based geopolymer with alkaline activator solution were investigated. The sodium hydroxide and sodium silicate were mixed together to form an alkaline ...
Reviews on the properties of aggregates made with or without geopolymerisation method
(Scientific.Net/Trans Tech Publications, 2012-12)
Aggregates are popular for use in concrete and lightweight concrete applications. Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight ...
Fly ash-based geopolymer lightweight concrete using foaming agent
(MDPI, Basel, Switzerland., 2012-06)
In this paper, we report the results of our investigation on the possibility of producing foam concrete by using a geopolymer system. Class C fly ash was mixed with an alkaline activator solution (a mixture of sodium ...
Characterization of LUSI mud volcano as geopolymer raw material
(Trans Tech Publications, 2012)
The mud of mud volcano samples were collected from an eruption site named 'LUSI' (Lumpur "mud" -Sidoarjo), East Java, Indonesia for characterization. Analysis showed that, the major constituents of mud are SiO 2 and Al 2O ...
