Methodological approach to recovery of the cracks on the turbine-shaft at hydroelectric power plant djerdap II
(Springer Netherlands, 2013)
In present paper, the methodological approach to analysis of the causes of failures and recovery of the damages has been presented using the example of the damage of the turbine-shafts construction. This approach can be ...
Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...
High-temperature concrete binders based on fly ash
(Revista Romana de Materiale/ Romanian Journal of Materials, 2013)
High-temperature concrete binders in which fly ash, as environmentally harmful secondary raw material, is combined with masonry and refractory cement is a new option for reapplication of this coal combustion by-product. ...
Geopolimeri na bazi alkalno aktiviranog elektrofilterskog pepela kao novo vezivo u betonu / Alkali activated fly ash geopolymers as a new binder in concrete
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2013)
U skladu sa rastućom brigom za zaštitu životne sredine i potrebom razvoja održivog građevinarstva, javlja se i veće interesovanje za istraživanja u oblasti novih materijala, koji će koristiti otpadne sirovine i imati manji ...
Evaluation of Lignite Fly Ash for Utilization as Component in Construction Materials
(Taylor & Francis Inc, Philadelphia, 2013)
Utilization potential of fly ash, as the main residue in the lignite coal combustion in Serbian power plants, was investigated in present study. High production of fly ash represents extreme hazard for environment. Question ...
Influence of FSW parameters on formation quality and mechanical properties of Al 2024-T351 butt welded joints
(Elsevier, Amsterdam, 2013)
The influence of R/v ratio on joint quality in 2024-T351 aluminum alloy was studied. Specimens were subjected to friction stir welding with the rotation rates of 750, 950 and 1180 r/min and welding speed between 73 and 190 ...
Sensitivity analysis of mathematical models for final product properties: Link to DTG curve
(Elsevier Sci Ltd, Oxford, 2013)
Compressive strength and water absorption of fired heavy clay products varies with firing temperatures, but not entirely according to linear function, as it is mostly reported in literature. Also, differential thermo-gravimetric ...
Failure investigation of the bucket wheel excavator crawler chain link
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The high mobility of open pit machines in heavy duty conditions provides fertile ground for the occurrence of various failures of the traveling mechanisms' vital parts such as chain links. The goal of the study presented ...
Explicit parametric method for optimal spur gear tooth profile definition
(Trans Tech Publications Ltd, 2013)
The gear tooth profile has an immense effect on the main operating parameters of gear pairs (load capacity, working life, efficiency, vibrations, etc). In current engineering research and practice, there is a strong need ...
Optimization of the production process through response surface method: Bricks made of loess
(Elsevier Sci Ltd, Oxford, 2013)
Loess clays are commonly used to produce bricks. Heavy clays, taken at location near Zrenjanin, Serbia, are used as a representative raw material in this study. The sample, containing about 28% of clay sized particles, is ...
