Characterization of geopolymer ceramic reinforced Sn-0.7Cu composite solder: effect of milling time and speed
(IOP Publishing Ltd, 2019-12)
The effect on the addition of optimally ball milled kaolin and fly ash geopolymer ceramic as reinforcement on the morphology and electrical properties of Sn-0.7Cu composite solder were explored. Geopolymer ceramics from ...
Influence of kaolin geopolymer ceramic additions to the wettability and electrical properties of Sn-3.0Ag-0.5Cu (SAC305) lead free solder
(IOP Publishing Ltd, 2019-12)
The effect of kaolin geopolymer ceramic addition to the wettability and electrical resistivity of Sn-3.0Ag-0.5Cu (SAC305) lead free solder was successfully explored. Powder metallurgy with microwave sintering method was ...
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 ...
Durability of metakaolin geopolymers with various sodium silicate/sodium hydroxide ratios against seawater exposure
(AIP Publishing, 2017-09)
This work presents an investigation of the performance of metakaolin geopolymers exposed to the continuous
immersion of seawater. The geopolymers were prepared from metakaolin by activating with a mixture of sodium ...
Thermal resistance variations of fly ash geopolymers: foaming responses
(Springer Nature Limited, 2017-03)
This paper presents a comparative study of the characteristic of unfoamed and foamed geopolymers after exposure to elevated temperatures (200–800 °C). Unfoamed geopolymers were produced with Class F fly ash and sodium ...
Effect of solid-to-liquid ratio on thin fly ash geopolymer
(IOP Publishing Ltd, 2020-02)
The present work studies the effect of solid-to-liquid (S/L) ratio on the properties of thin fly ash-based geopolymer. The fly ash geopolymers with dimension of 160 mm × 40 mm × 10 mm were synthesised by using various S/L ...
Corrosion studies of fly ash and fly ash-slag based geopolymer
(IOP Publishing Ltd, 2017-06)
This paper presents the results of corrosion studies between Fly Ash Geopolymer (FG) paste and Fly Ash-Slag Geopolymer (FSG) paste. Geopolymer was made from aluminosilicate inorganic polymers mixed with the alkaline activator ...
Correlation of the processing parameters in the formation of granulated ground blast furnace slag geopolymer
(IOP Publishing Ltd, 2017-06)
Geopolymers are inorganic materials with huge potential applications including building material, fire resistant materials, and agricultural construction materials. Various parameters influenced the final properties of ...
Influence of kaolin in fly ash based geopolymer concrete: destructive and non-destructive testing
(IOP Publishing Ltd, 2018-06)
Development of geopolymer concrete is mainly to reduce the production of ordinary Portland cement (OPC) that adverse the natural effect. Fly ash is a by-product collected from electrical generating power plant which resulted ...
Durability of fly ash based geopolymer concrete infilled with rubber crumb in seawater exposure
(IOP Publishing Ltd, 2018-06)
Geopolymer is an alternative binder to replace Ordinary Portland Cement (OPC)in construction industry. Source materials that rich in silica (Si) and alumina (Al) were activated by using alkaline solution. Production of ...
