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 ...
The Utilization of Unsaleable Lignite Fines at Eskisehir Koyunagili Region Lignite Deposits
(Taylor & Francis Inc, 2012)
Samples taken from stock piles of Koyunagili Lignites Company preparation plant were cleaned by means of gravity methods to obtain a saleable product. The optimum conditions of separation were determined under the laboratory ...
Floatability of Eskisehir Koyunagili Region Lignite Fines
(Int Scientific Conference Sgem, 2010)
In this work, samples were taken from Koyunagili Lignites Company Washing Plant feed and were subjected to extensive research to determine the floatability of lignite fines. The optimum conditions of flotation were determined ...
Ion imprinted cryogel-based supermacroporous traps for selective separation of cerium(III) in real samples
(Elsevier Science BV, 2018)
This study demonstrates the preparation and characterization of a novel ion imprinted cryogel which exhibits high affinity and selectivity towards Ce(III) ions in aqueous solutions and bastnasite ore samples. 2-Hydroxyethyl ...
Desulphurization of lignites by slow, fast, and flash pyrolysis and high intensity dry magnetic separation
(Taylor & Francis Inc, 2007)
Slow, fast and flash pyrolysis followed by high intensity dry magnetic ( HIDM) separation experiments were conducted to obtain improved solid fuels. Pyrolysis experiments were performed in three different apparatus, and ...

In the last decade, nanotechnology has inspired in an extraordinary manner to the world and established an interdisciplinary trend between almost all branches of science and technology. It is expected that within no time ...
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, ...
An Experimental Analysis of Air Source Heat Pump Water Heater
(Turkish Soc Thermal Sciences Technology, 2012)
Heating and cooling are one of the fundamental research area for the engineers. Due to increment of the energy demand and decrement on the sources leads the researchers to develop the recent systems and find out new systems. ...
Bearing Capacity and pH Value of Stabilized Soils with Class F Fly Ash and Cement
(Springer International Publishing Ag, 2018)
The California Bearing Ratio (CBR) test determines behaviour of road sub-base and granular layers for flexible pavement. In the conventional CBR test, compacted sample was waited in air for 24 h and in water for 4 days. ...
A stochastic model for the capacity estimation of non-seismically designed beam-column joints
(Czech Technical University, 2018)
An analytical model based on nonlinear fracture mechanics was employed to evaluate the shear capacity of a substandard beam-column joint retrofitted by externally applied post-tensioned bars. The strength of the reference ...
