Review on fly ash-based geopolymer concrete without portland cement
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper summarizes the factors that affect the properties of fly ash-based geopolymer concrete. Alkaline activator is an important material that controls the properties of geopolymer concrete. The workability of fresh ...
Nano geopolymer for sustainable concrete using fly ash synthesized by high energy ball milling
(Trans Tech Publications, 2013)
This paper presents the development of a nano geopolymer for sustainable concrete using fly ash synthesized by high-energy ball milling. In this paper, we report on our investigation of the effects of grinding on the binder ...
The processing, characterization, and properties of fly ash based geopolymer concrete
(Advanced Study Center Co. Ltd, 2012)
In recent years, attempts to increase the utilization of fly ash as a replacement for ordinary Portland cement (OPC) in concrete have increased in significance. Geopolymer concrete does not need the presence of Portland ...
Study on physical and chemical properties of fly ash from different area in Malaysia
(Trans Tech Publications, 2013-12)
Fly ash is residue from the combustion of coal which widely available in worldwide and lead to waste management proposal. Moreover, the use of fly ash is more environmental friendly and save cost compared to OPC. Fly ash ...
Mechanical performances of fly ash geopolymer bricks
(American Scientific Publishers, 2013-01)
Geopolymer is a new class of three-dimensionally networked amorphous to semi-crystalline alumino-silicate materials, and first developed by Professor Davidovits in 1978. Geopolymers can be synthesized by mixing alumino-silicate ...
Lightweight fly ash-based geopolymer concrete
(Trans Tech Publications, 2013)
The experiments of this study were preformed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) using normal sand as a fine aggregate and expanded clay as lightweight aggregate. The LWAGC ...
The influence of curing periods on the compressive strength of fly ash-based geopolymer at different aging times
(Trans Tech Publications, 2012)
The results of the current experimental investigation indicate the significant effect of the heating periods on the compressive strength of fly ash-based geopolymers prepared at different alkaline liquid content at both ...
Effect of fly ash/alkaline activator ratio and sodium silicate/NaoH ratio on fly ash geopolymer coating strength
(Trans Tech Publications, 2013)
Fly ash geopolymer coating material potential used to protect surface used in exposure conditions. Ratio of fly ash/alkaline activator and Na₂SiO₃/NaOH play important parameter on determining the best flexural strength of ...
Compressive strength of fly ash based geopolymer / glass fiber composite via filament winding
(Trans Tech Publications, 2014)
In general, filament winding technique is used to fabricate the composite pipes using continuous fiber and matrix resin. In this study, fly ash based geopolymer resin composites reinforced by continuous glass fiber were ...
Compressive strength and morphology of fly ash based geopolymer as artificial aggregate with different curing temperature
(Trans Tech Publications, 2014)
This paper presented the compressive strength of geopolymer paste with different NaOH concentration and morphology analysis for sintered artificial aggregate. This artificial aggregate was produce based on mix design with ...
