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 ...
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 ...
Design, processing and characterization of fly ash-based geopolymers for lightweight concrete application
(Institute for Scientific Information (ISI), 2013-04)
The mix design of geopolymers plays important role in obtaining desirable compressive strength. Optimum mix design of geopolymers can be applied for application, such as lightweight concrete. In order to determine the ...
Comparison of geopolymer fly ash and ordinary Portland cement to the strength of concrete
(American Scientific Publishers, 2013-12)
The aim of this study is to evaluate the effect of various fly ash: aggregate ratios by using fly ash (FA) based geopolymer compared to ordinary Portland cement (OPC) on the compressive strength of concrete. The different ...
Reviews on the Geopolymer materials for coating application
(Scientific.Net, 2012-12)
The application of geopolymer has been expand in many areas where before this it only used for the production of cement and concrete. One of the new applications of geopolymer is for coating. Metakaolin, fly ash and ...
Microstructure studies on the effect of the alkaline activators of fly ash-based geopolymer at elevated heat treatment temperature
(Trans Tech Publications, 2013)
Fly ash-based geopolymers are new binding materials produced to replace the ordinary Portland cement (OPC) used in concrete. In this research, the effect of alkaline activators on the compressive strength and the microstructure ...
Study on radioactivity components, water quality and microstructure characteristic of volcano ash as geopolymer artificial aggregate
(SYSCOM 18, 2013-06)
The assessments of radioactivity, water qualitytesting and microstructure characteristic of volcano ash have been examined. The measurement of the 226Ra, 232Th, 40K, and 238U were carried out using radioactive concentration ...
