Self-Fluxing Mechanism in Geopolymerization for Low-Sintering Temperature of Ceramic
(MDPI AG, 2021-03-10)
Kaolin, theoretically known as having low reactivity during geopolymerization, was used as a source of aluminosilicate materials in this study. Due to this concern, it is challenging to directly produce kaolin 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 ...
Effect of aluminium powder on kaolin-based geopolymer characteristic and removal of Cu²⁺
(MDPI AG, 2021-02)
This current work focuses on the synthesis of geopolymer-based adsorbent which uses kaolin as a source material, mixed with alkali solution consisting of 10 M NaOH and Na₂SiO₃ as well as aluminium powder as a foaming agent. ...
Role of sintering temperature in production of nepheline ceramics-based geopolymer with addition of ultra-high molecular weight polyethylene
(MDPI AG, 2021-02)
The primary motivation of developing ceramic materials using geopolymer method is to minimize the reliance on high sintering temperatures. The ultra-high molecular weight polyethylene (UHMWPE) was added as binder and ...
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 ...
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 ...
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 ...
