Kaya, Selvin Yeşilay; Karasu, Bekir (Elsevier Sci LTD, 2012)In this study bluish-green (BG) and yellowish-green (YG) phosphorescent pigments were synthesized and produced under laboratory conditions and the best ones in terms of higher phosphorescence intensity and longer duration ... -
Production of opaque frits with low ZrO2 and ZnO contents and their industrial uses for fast single-fired wall tile glazes
Pekkan, K.; Karasu, Bekir (Springer, 2009)The amounts of zirconium and zinc oxides, which raise the production costs of ceramic glazes, were decreased in fast single-fired wall tile frit compositions and an industrial frit production was conducted. Opacity of the ... -
The suitability for using glass and fly ash in Portland cement concrete
Tuncan, Mustafa; Karasu, Bekir; Yalçın, Muhsin (International Society Offshore& Polar Engineers, 2001)The utilization of glass and fly ash as additives in concrete introduces many benefits from technical and environmental points of view. Change in the compressive strength of concrete depends on the aggregate-cement ... -
Usability of industrial ashes in cement production as pozzolanic materials
Kavas, Taner; Karasu, Bekir; Arslan, Özlem (Minerals, Metals & Materials Soc, 2006)In the present study the utilization of coal ashes that appear at the end of firing process of brick production in cement pastes was examined. Ashes with three different particle sizes of 75 gm, 106 pm and 150 gm were used ... -
The usage of newly developed glass fibre in cement structure and their characterization
Yurdakul, Arife; Dolekcekic, Emrah; Günkaya, Göktuğ; Kavas, Taner; Karasu, Bekir (Elsevier Sci LTD, 2018)In this work, recently developed Zrnl glass fibres belonging to the SrO-Mn2O3-Fe2O3-MgO-ZrO2-SiO2 (SMFMZS) system have been used as reinforcing materials in cement. The highest (2.610 N/mm(2)) compressive strength value ... -
