Influence of solid-to-liquid ratio on properties of fly ash geopolymer ceramics
(IOP Publishing Ltd, 2019-08)
Ceramics has come to be progressively very important in industry because of their exceptional mechanical and physical properties The motivation to develop fly ash geopolymer ceramics was to overcome the problem associated ...
Effects of thermal resistance to fly ash-based lightweight geopolymer
(IOP Publishing Ltd, 2019-08)
Geopolymers are inorganic polymeric materials and cementations materials that replace the Ordinary Portland Cement. This study aimed to determine the effect of thermal resistance of fly ash based lightweight geopolymer and ...
Performance of geopolymer concrete when exposed to marine environment
(IOP Publishing Ltd, 2019-07)
Over the decades, concrete is widely known as the most resourceful construction material as it is suitable for many building applications. However, despite its ability to last hundreds of years in many applications, it has ...
Mechanical properties and thermal conductivity of lightweight foamed geopolymer concretes
(IOP Publishing Ltd, 2019-08)
Foamed geopolymer concretes have a better performance in the thermal insulation properties compared to normal geopolymer concretes. In this research, lightweight aggregate geopolymer concretes was incorporated with different ...
Porous metakaolin geopolymers with tailored thermal conductivity
(IOP Publishing Ltd, 2019-08)
In this work, a novel lightweight metakaolin geopolymers were produced by using hydrogen peroxide as foaming agent. The influence of the hydrogen peroxide incorporation content (0.25 – 1.25%) on density, compressive strength ...
Mesoporous structure of doped and undoped PEG on Ag/TiO₂ thin film
(IOP Publishing Ltd, 2019-08)
In this reaserch, photocatalyst silver titanium dioxide was doped and modified by Polyethylene Glycol (PEG). The purpose of the present study was to analyse the synthesized Ag/TiO₂ thin film doped and undoped PEG. Ag/TiO₂ ...
Correlation of microstructure and flexural strength of fly ash geopolymer of varying molarities
(IOP Publishing Ltd, 2019-08)
The present work studies and compares the flexural properties of fly ash geopolymer with varying molarity of sodium hydroxide (NaOH). Different molarities of NaOH solution (6M, 8M, 10M, 12M and 14M) are used to prepare the ...
Optimization of processing parameters for graphitization of oil palm trunk waste at lower heating temperature
(IOP Publishing Ltd, 2019-07)
Previously synthetic graphite was produced at higher temperature which is around 2,500°C in complex processing method. The method bear the name of the scientist whose discover the synthetic graphite namely "Acheson Process". ...
Microstructural analysis of fly ash-based geopolymers with various alkali concentration
(IOP Publishing Ltd, 2019-08)
In the present work, a comparative study on the effect of different concentration of sodium hydroxide (NaOH) on fly ash-based geopolymer was investigated. The geopolymer synthesis by mixing fly ash with alkali activator ...
