Fly ash-based geopolymer lightweight concrete using foaming agent
(MDPI, Basel, Switzerland., 2012-06)
In this paper, we report the results of our investigation on the possibility of producing foam concrete by using a geopolymer system. Class C fly ash was mixed with an alkaline activator solution (a mixture of sodium ...
Effect on strength and hardness of clay ceramic substrate after treatment using koalin based geopolymer glaze
(Trans Tech Publications, 2014)
Geopolymerization is an alternative for ceramic industry by using clay based material such as kaolin or calcined kaolin geopolymer. Geopolymer paste is initially produced by alkaline activation of calcined kaolin with NaOH ...
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 ...
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 ...
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 ...
Review on the various ash from palm oil waste as geopolymer material
(Advanced Study Center Co. Ltd., 2013)
The solid waste from palm oil mill industry has been increasing annually where it has been reported that the palm oil waste was produced 4 million tons/years in Malaysia only. Hence, the solution to overcome the problems ...
Feasibility of producing wood fibre-reinforced geopolymer composites (WFRGC)
(Trans Tech Publications, 2013)
Wood fibres have long been known as a fibre reinforcement for concrete. Due to its availability and low production cost, this natural fibre has been used in less developed country where conventional construction materials ...
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 ...
Correlation between Na 2SiO 3/NaOH ratio and fly ash/alkaline activator ratio to the strength of geopolymer
(Trans Tech Publications, 2012)
Geopolymer requires an alkaline activator to induce it pozzolanic property and to accelerate the geopolymerisation process. The geopolymerisation process occurs due to the mixing of fly ash, sodium silicate and sodium ...
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 ...
