(IOP Publishing Ltd, 2019-07)
The preparation and characterization of glass reinforced epoxy filled with different weight percentage of geopolymers filler attained from fly ashand epoxy resins are reported limited of study. Recent glass reinforced epoxy ...
Investigation of heat released during geopolymerization with fly ash based geopolymer
(IOP Publishing Ltd, 2019-08)
Geopolymerization consists of several chemical reactions that has been reported widely as an exothermic reaction. Previous studies on heat released during geopolymerization used metakaolin and fly ash of F class as a ...
Bond strength mechanism of fly ash based geopolymer mortars: a review
(IOP Publishing Ltd, 2017-11)
Geopolymer possess many excellent properties such as high compressive and bond strength, long term durability, better acid resistance and also known as a "Sustainable Material" due to its low carbon emission and low energy ...
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 ...
Contribution of interfacial bonding towards geopolymers properties in geopolymers reinforced fibers: a review
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-02-17)
There is a burgeoning interest in the development of geopolymers as sustainable construction materials and incombustible inorganic polymers. However, geopolymers show quasi-brittle behavior. To overcome this weakness, ...
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, ...
Effect of different ratio of geopolymer paste based fly ash-metakaolin on compressive strength and water absorption
(IOP Publishing Ltd, 2019-12)
This paper presents the effect of different solid to solid (S/S) ratio by mixing the fly ash and metakaolin as geopolymer paste on the compressive strength and water absorption. Fly ash is a waste materials produced by ...
Characterisation at the bonding zone between fly ash based geopolymer repair materials (GRM) and ordinary portland cement concrete (OPCC)
(MDPI AG, 2020-12)
In recent years, research and development of geopolymers has gained significant interest in the fields of repairs and restoration. This paper investigates the application of a geopolymer as a repair material by implementation ...
Bonding strength characteristics of FA-based geopolymer paste as a repair material when applied on OPC substrate
(MDPI AG, 2020-05)
This investigative study aims to study the mechanical and morphological properties of fly ash (FA)-based geopolymer paste as a repair material when applied on ordinary Portland cement (OPC) overlay concrete. The first part ...
Evaluation of the effect of silica fume on amorphous fly ash geopolymers exposed to elevated temperature
(MDPI AG, 2021-01)
The properties of amorphous geopolymer with silica fume addition after heat treatment was rarely reported in the geopolymer field. Geopolymer was prepared by mixing fly ash and alkali activator. The silica fume was added ...
