Manufacturing of fire resistance geopolymer: a review
(EDP Sciences, 2016)
Protection against fire using inorganic polymer is a new application of engineering technology. Even though, there are varieties of fire-protection materials, there is always a need for the development of new materials ...
Review of Dolomite as precursor of Geopolymer materials
(EDP Sciences, 2016)
Geopolymer is an environmentally friendly cementitious binder that does not require the existence of ordinary Portland cement (OPC). Geopolymer has many excellent advantages, including high early strength, low shrinkage, ...
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 effects of various concentrations of NaOH on the inter-particle gelation of a fly ash geopolymer aggregate
(MDPI AG, 2021-02)
Aggregates can be categorized into natural and artificial aggregates. Preserving natural resources is crucial to ensuring the constant supply of natural aggregates. In order to preserve these natural resources, the production ...
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 ...
