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, ...
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 ...
