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 ...
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 ...
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 ...
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 ...
