Temmoku sırları
(Anadolu Üniversitesi, 2012)
Temmoku sırlar keşfedildiğinden bu yana, en önemli sırlardan biri olmuştur. Temmoku sırların üretimi, Çin’de Sung (960–1279) hanedanlığı döneminde siyah ve kahverengi sırların üretimi ile başladı. Sung Hanedanlığı döneminde ...
Isolation and characterization of native microorganism from Turkish lignite and usability at fungal desulphurization
(Elsevier Sci LTD, 2014)
In this study, microorganisms were isolated from Mihaliccik region (Eskisehir, Turkey) lignites with low rank and high ash and sulphur content. A series of heavy liquids (from 1.3 g/ml to 1.9 g/ml) were used to determine ...
Evaluation of combined lignite cleaning processes, flotation and microbial treatment, and its modelling by Box Behnken methodology
(Elsevier Sci LTD, 2017)
In this study, first, the physicochemical cleaning of Cayirhan region's low-quality lignites was investigated by flotation to reduce ash content. In the flotation experiments, the effects of collector dosage, frother dosage, ...
Physical and physicochemical cleaning of lignite and the effect of cleaning on biodesulfurization
(Elsevier Sci LTD, 2014)
In this work, physical, physicochemical and biological processes were combined to decrease the sulfur and ash content of finely ground coal. Two separation methods - flotation and a multigravity separator (MGS) - were ...
Recycling of coal combustion wastes
(SAGE Publications LTD, 2009)
The separation of unburned carbon from coal-fired power plant bottom ashes was conducted in order to increase the possibility of the recycling of coal combustion wastes. A two-stage flotation technique was used for this ...
Conversion of coal-fired bottom ash to fuel and construction materials
(Taylor & Francis LTD, 2017)
In this study, solid wastes taken from Seyitomer coal-fired power plant bottom ashes were subjected to experimental research to obtain a carbon-rich fraction. The possible recycling opportunities of remaining inorganic ...
The effect of ground granulated blast-furnace slag on properties of Horasan mortar
(Elsevier Sci LTD, 2013)
Mortars containing brick or tile powder and lime are called Horasan mortar in Ottoman and Cocciopesto in ancient Roman. In this study, ground granulate blast-furnace slag was used in Horasan mortars to obtain improvements ...
Improvement of Khorasan mortar with fly ash for restoration of historical buildings
(Walter De Gruyter GMBH, 2014)
In this study, the effects of fly ash on Khorasan mortar composed of brick or tile powder and lime were investigated to improve its mechanical properties. In the mixtures, fly ash was used instead of 0- to 4-mm crushed ...
The effect of cover thickness on rebars exposed to elevated temperatures
(Elsevier Sci LTD, 2008)
In this study, the mechanical properties of structural rebars have been investigated after exposure of elevated temperatures. The mortar was prepared with CEM I 42.5N cement and fired clay. The S 420a, circle divide 16 mm ...
Effect of expanded perlite aggregate on the properties of lightweight concrete
(Elsevier Science Sa, 2008)
Expanded perlite aggregate (EPA) is a heat and sound insulator, and lightweight material which ensures economical benefits in constructions. This paper investigates the properties of concrete containing EPA considering ...
