Effect of sodium hydroxide molarity on physical, mechanical and thermal conductivity of metakaolin geopolymers
(IOP Publishing Ltd, 2018-03)
In the present work, the effect of different sodium hydroxide (NaOH) molarity (6M, 8M, 10M, 12M and 14M) on the physical, mechanical and thermal conductivity of metakaolin geopolymers (MkGPs) was investigated. Geopolymers ...
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 ...
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 ...
Strength, density and water absoprtion of Palm oil boiler ash (POBA) geopolymer brick/IBS brick
(Trans Tech Publications Ltd., 2016-01)
Geopolymer or alkali-activated binder is produced by synthesizing aluminosilicate source materials with an alkaline activator solution. This study has been conducted to produce palm oil boiler ash (POBA) geopolymer brick/IBS ...
Morphology and properties of geopolymer coatings on glass fibre-reinforced epoxy (GRE) pipe
(EDP Sciences, 2016)
Geopolymer coatings were coated on glass fibre-reinforced epoxy (GRE) pipe by using kaolin, white clay and silica sand as source materials and sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) as alkaline solution. The ...
