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 ...
Study on physical and chemical properties of fly ash from different area in Malaysia
(Trans Tech Publications, 2013-12)
Fly ash is residue from the combustion of coal which widely available in worldwide and lead to waste management proposal. Moreover, the use of fly ash is more environmental friendly and save cost compared to OPC. Fly ash ...
Review on the utilization of palm ash for geopolymer composite
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
The waste materials from agro industry can be use as pozzolanic material in concrete production. One of the agro waste materials that have possibility is palm ash because it has been used up to 60% for cement replacement. ...
Corrosion performance of reinforcement bar in geopolymer concrete compare with its performance in ordinary portland cement concrete: A short review
(Trans Tech Publications, 2013)
Since decades ago, corrosion is the crucial factors for million dollars loss in construction industry. Corrosion of reinforcement bar in ordinary Portland cement (OPC) concrete is mainly due to chloride and acid attack and ...
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 ...
The effect of damp sand content on the geopolymerization reaction of fly ash-based geopolymer mortars
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
The results of the current experimental investigation indicates the significant effect of the
natural sand content prepared in damp condition on the compressive strength of fly ash-based
geopolymer mortars prepared at ...
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 ...
A study on the synthesis of fly ash-based lightweight aggregate geopolymer concrete
(American Scientific Publishers All rights reserved., 2013-01)
The experiments conducting for current investigation aimed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) and explore the significance and limitations of the activator content on the ...
