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 ...
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 ...
