Geopolymers and their uses: review
(IOP Publishing Ltd, 2018-06)
Outlining the past-present history of the study of alumino-silicate materials, it is well known that geopolymers are inorganic polymers obtained from chemical reaction, also known as geopolymerisation, between an alkaline ...
The effect of baggase ash on fly ash-based geopolimer binder
(IOP Publishing Ltd, 2018-06)
Geopolymer concrete is an environmentally friendly concrete. However, the geopolymer binder has a problem with setting time; mainly the composition comprises high calcium fly ash. This study utilized bagasse ash to improve ...
Effect of mixing temperature on characteristics of thermoplastic potato starch film
(IOP Publishing Ltd, 2018-06)
This study present the preparation of potato starch film with glycerol as a plasticizer through a solution casting technique. The effect of mixing temperature (80°C, 85°C, 90°C and 95°C) on the tensile and microstructure ...

Mechanical and physical properties of bottom ash/fly ash geopolymer for pavement brick application
(IOP Publishing Ltd, 2020-02)
Geopolymers are amorphous to semi-crystalline with excellent physical and and mechanical properties. It has been used to become a potential binder to Ordinary Portland Cement (OPC) in certain applications due to its lower ...
In Vitro bioactivity study of thermoplastic Starch/Bentonite/Hydroxyapatite composites for biomedical applications
(IOP Publishing Ltd, 2020-02)
Potato starch composites film incorporating hybrid bentonite and hydroxyapatite (HA) were investigated as novel biomaterial for potential biomedical applications. The selected potato starch/bentonite composites were prepared ...
Compressive strength and thermal conductivity of metakaolin geopolymers with anisotropic insulations
(IOP Publishing Ltd, 2020-02)
This research investigated the properties of thermally insulating geopolymer prepared using waste filler (fibreboard and rubber) to act as anisotropic pore/insulation. The geopolymer matrix was synthesised using metakaolin ...
