The influence of pre-heated treatment to improve adhesion bond coating strength of fly ash based geopolymer ceramic
(IOP Publishing Ltd, 2018-06)
The study focus on effect of pre-heated ceramic surface on the adhesion bond strength between geopolymer coating coating and ceramic substrates. Ceramic substrates was pre-heated at different temperature (400 °C, 600 °C, ...
Durability of metakaolin geopolymers with various sodium silicate/sodium hydroxide ratios against seawater exposure
(AIP Publishing, 2017-09)
This work presents an investigation of the performance of metakaolin geopolymers exposed to the continuous
immersion of seawater. The geopolymers were prepared from metakaolin by activating with a mixture of sodium ...
Thermal resistance variations of fly ash geopolymers: foaming responses
(Springer Nature Limited, 2017-03)
This paper presents a comparative study of the characteristic of unfoamed and foamed geopolymers after exposure to elevated temperatures (200–800 °C). Unfoamed geopolymers were produced with Class F fly ash and sodium ...
Effect of solid-to-liquid ratio on thin fly ash geopolymer
(IOP Publishing Ltd, 2020-02)
The present work studies the effect of solid-to-liquid (S/L) ratio on the properties of thin fly ash-based geopolymer. The fly ash geopolymers with dimension of 160 mm × 40 mm × 10 mm were synthesised by using various S/L ...
Strength development and elemental distribution of dolomite/fly ash geopolymer composite under elevated temperature
(MDPI AG, 2020-02)
A geopolymer has been reckoned as a rising technology with huge potential for application across the globe. Dolomite refers to a material that can be used raw in producing geopolymers. Nevertheless, dolomite has slow ...
Corrosion studies of fly ash and fly ash-slag based geopolymer
(IOP Publishing Ltd, 2017-06)
This paper presents the results of corrosion studies between Fly Ash Geopolymer (FG) paste and Fly Ash-Slag Geopolymer (FSG) paste. Geopolymer was made from aluminosilicate inorganic polymers mixed with the alkaline activator ...
Effect of alkali concentration on fly ash geopolymers
(IOP Publishing Ltd, 2018-03)
This paper presents the effect of NaOH concentration on fly ash geopolymers with compressive up to 56 MPa at 12M. The physical and mechanical on fly ash geopolymer are investigated. Test results show that the compressive ...
Compressive strength and thermal conductivity of metakaolin geopolymers with anisotropic insulations
(IOP Publishing Ltd, 2020-02)
This research investigated the properties of thermally insulating geopolymer prepared using waste filler (fibreboard and rubber) to act as anisotropic pore/insulation. The geopolymer matrix was synthesised using metakaolin ...
Effect of Glass Reinforced Epoxy (GRE) pipe filled with Geopolymer Materials for Piping Application: Compression Properties
(EDP Sciences, 2016)
The aim of this paper is to achieve the highest compressive strength of glass reinforced epoxy pipe with the geopolymer filler content of weight percentage that were used in glass reinforced epoxy pipe. The samples were ...
The effect of curing temperature on physical and chemical properties of geopolymers
(Elsevier BV, 2011)
Fly ash-based geopolymers required heat to increase the geopolymerization process in order to obtain higher compressive strength. As such, geopolymer samples were prepared using different curing temperatures (room temperature, ...
