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 ...
Review of the characterization and processing of palm ash as a geopolymer composite
(American Scientific Publishers, 2013-01)
Malaysia is the world's largest producer and exporter of palm oil and it produces a million tons of palm oil waste annually. Palm ash is a by-product from the use of palm oil shells and palm oil bunches, which are used to ...
Effect of NaOH concentration on microstructure of boiler ash based geopolymer
(Trans Tech Publications Ltd., 2015)
Boiler ash is one of the waste material from palm oil processing industry and it was widely available. The role of alkaline activator in geopolymer is important for its mechanical properties. NaOH and sodium silicate ...
Chemical and physical characterization of boiler ash from palm oil industry waste for geopolymer composite
(Syscom 18 SRL/ SC BIBLIOTECA CHIMIEI SA, 2013-12)
The characterizations of boiler ash waste from waste of palm oil industry were performed. The boiler ash was obtained from the boiler in the palm oil processing factory. The chemical and physical characterization has been ...
Microstructure study on optimization of high strength fly ash based geopolymer
(Trans Tech Publications, 2012)
The compressive strength and microstructural characteristics of fly ash based geopolymer with alkaline activator solution were investigated. The sodium hydroxide and sodium silicate were mixed together to form an alkaline ...
Microstructure study on volcano ash geopolymer aggregate at different sintering temperature
(Trans Tech Publications, 2014)
Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight aggregates. The usage of this material can improve the quality of the aggregates ...
Influence of dolomite on the mechanical properties of boiler ash geopolymer paste
(Trans Tech Publications, 2014)
The waste material from palm oil industry has been increasing since Malaysia was the world largest exported of palm oil mill. The waste such as palm fibers, nut shells, palm kernel and empty fruit bunches are the solid ...
The relationship of NaOH molarity, Na2SiO3/NaOH ratio, fly ash/alkaline activator ratio, and curing temperature to the strength of fly ash-based geopolymer
(Trans Tech Publications, 2011)
Geopolymer, produced by the reaction of fly ash with an alkaline activator (mixture of Na2SiO3 and NaOH solutions), is an alternative to the use of ordinary Portland cement (OPC) in the construction industry. However, there ...
Effect of Solids-To-Liquids, Na2SiO3-To-NaOH and Curing Temperature on the Palm Oil Boiler Ash (Si + Ca) Geopolymerisation System
(MDPI AG, 2015)
This paper investigates the effect of the solids-to-liquids (S/L) and Na2SiO3/NaOH ratios on the production of palm oil boiler ash (POBA) based geopolymer. Sodium silicate and sodium hydroxide (NaOH) solution were used as ...
