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 ... -
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 ... -
The effect of curing temperature on physical and chemical properties of geopolymers
(Elsevier BV, 2011)Fly ash-based geopolymers required heat to increase the geopolymerization process in order to obtain higher compressive strength. As such, geopolymer samples were prepared using different curing temperatures (room temperature, ... -
The effects of various concentrations of NaOH on the inter-particle gelation of a fly ash geopolymer aggregate
(MDPI AG, 2021-02)Aggregates can be categorized into natural and artificial aggregates. Preserving natural resources is crucial to ensuring the constant supply of natural aggregates. In order to preserve these natural resources, the production ... -
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 ... -
Reviews on the different sources materials to the geopolymer performance
(AENSI Publisher All rights reserved, 2013-10)Geopolymer is manufactured from the aluminosilicate source material in example fly ash, silica fume, kaolin, ground granulate blast slag (GGBS), boiler ash and volcano ash reactivated via alkaline solution. But the different ...
