General properties of kaolin geopolymers
(American Scientific Publishers, 2013-01)
This paper reported the properties of kaolin geopolymers in term of the bulk density, compressive strength, qualitative observation and SEM analysis of the kaolin geopolymers. Kaolin geopolymers were synthesized through ...
Kaolin-based geopolymers with various NaOH concentrations
(Springer Verlag, 2013-03)
Kaolin geopolymers were produced by the alkali-activation of kaolin with an activator solution (a mixture of NaOH and sodium silicate solutions). The NaOH solution was prepared at a concentration of 6-14 mol/L and was mixed ...
Influence of oxide molar ratios on kaolin geopolymers
(American Scientific Publishers, 2013-12)
Oxide molar ratios are the main key parameter determining the performance of a kaolin geopolymers. The kaolin composition and various mixture proportions will lead to different oxide molar ratios in geopolymer system. In ...
Mechanical and microstructural evaluations of lightweight aggregate geopolymer concrete before and after exposed to elevated temperatures
(MDPI, Basel, Switzerland, 2013)
This paper presents the mechanical and microstructural characteristics of a lightweight aggregate geopolymer concrete (LWAGC) synthesized by the alkali-activation of a fly ash source (FA) before and after being exposed to ...
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 ...
Design, processing and characterization of fly ash-based geopolymers for lightweight concrete application
(Institute for Scientific Information (ISI), 2013-04)
The mix design of geopolymers plays important role in obtaining desirable compressive strength. Optimum mix design of geopolymers can be applied for application, such as lightweight concrete. In order to determine the ...
Comparison of geopolymer fly ash and ordinary Portland cement to the strength of concrete
(American Scientific Publishers, 2013-12)
The aim of this study is to evaluate the effect of various fly ash: aggregate ratios by using fly ash (FA) based geopolymer compared to ordinary Portland cement (OPC) on the compressive strength of concrete. The different ...
Feasibility of producing wood fibre-reinforced geopolymer composites (WFRGC)
(Trans Tech Publications, 2013)
Wood fibres have long been known as a fibre reinforcement for concrete. Due to its availability and low production cost, this natural fibre has been used in less developed country where conventional construction materials ...
