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 ...
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 ...
Cyclic Oxidation Behaviour of MoSi2 and MoSi2-Si3N4 Composites for Aircraft Gas Turbine Elements
(Trans Tech Publications LTD, 2011)
Pest oxidation phenomena is the major drawback of MoSi2 for the applications of this material over gas turbine elements. Therefore, addition of Si3N4 does not only eliminate the structural disintegration behaviour which ...
Effect of curing time on selected properties of soil stabilized with fly ash, marble dust and waste sand for road sub-base materials
(SAGE Publications LTD, 2017)
The properties of sub-base filling materials in highway construction are essential, as they can determine the performance of the road in service. Normally, the existing materials are removed and replaced with new materials ...
Determination of synergetic effect in co-pyrolysis of lignite and waste tyre
(Elsevier Sci LTD, 2015)
An attempt was made to investigate potential synergistic activities between waste tyre and lignite during co-pyrolysis. The parameters such as blending ratios of waste tyre and lignite, final pyrolysis temperature, heating ...
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 ...
Electron beam welding varestraint test of ALLVAC 718 Plus™ for aviation technology
(2012)
The improvements of materials used in aircraft gas turbine engines which constitute 50% of total aircraft weight must protect its actuality continuously. Utilization of super alloys in aerospace and defense industries can ...
Effects of Catalyst on Pyrolysis of Laurel (Laurus Nobilis L.) Seed in a Fixed Bed Tubular Reactor
(Aidic Servizi Srl, 2014)
In this study, the daphne seed (Laurus nobilis L.) was used as biomass sample for catalytic pyrolysis using (Ni/Al2O3) commercial catalyst (Criterion-454) in the nitrogen atmosphere. Experimental studies were conducted in ...
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 ...
Structural characterization of glass-ceramics made from fly ash containing SiO2-Al2O3-Fe2O3-CaO and analysis by FT-IR-XRD-SEM methods
(Elsevier Science BV, 2012)
The glass-ceramics has been proposed as a useful recycling fly ash from thermal power plants. In this study, C type fly ash containing SiO2-Al2O3-Fe2O3-CaO has been sintered to form glass-ceramic materials at different ...
