Abstract
by sintering at different temperatures after alkali activation by geopolymerization, made from fly ash obtained from Sivas Kangal Thermal Power Plant, are discussed. Compression test for mechanical properties, transient plane source measurement for thermal properties, scanning electron microscopy for surface and powder properties, and X-ray diffraction for phase analysis were used. In studies, Na 2 SiO 3 , an alkali that can be found easily commercially and a source of silica, was used at different molarities and its properties were investigated. It was concluded that fly ash can be used both as a geopolymer and as a sintered material as a lateral plate as well as brick production. Compressive strength was found to be as 10 MPa, thermal conductivity is 0.0006 W/m.K, and the determined phases are calcium silicate, calcium aluminate, amorphous silica and magnesium aluminate and glassy kyanite which is a sintering product, namely aluminasilicate phase.
期刊介绍：
Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
