(Berg Fac Technical Univ Kosice, Kosice, 2013)
Five Tertiary granitoid plutons of central and western Serbia Vardar zone are examined in order to establish their potentiality for use as dimension stone. Field studies aimed at establishing the geological factors - ...
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 ...
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 ...
The influence of corrosion on stress concentration factor at shaft to flange radius
(Springer Netherlands, 2013)
This paper describes the influence of corrosion on stress concentration factor and crack initiation at shaft-flange transition section. The real turbine shaft failure case study is used for research. This case study and ...
Opekarske gline iz Srbije - primena u proizvodnji grube keramike / Serbian heavy clays behavior: Application in rough ceramics
(Savez hemijskih inženjera, Beograd, 2013)
Gline i glineni minerali se, usled mnogih specifičnih osobina pre i nakon pečenja, decenijama koriste kao osnovni materijali za proizvodnju grube keramike. Proučavanje i utvrđivanje mineralnih faza koje su prisutne u ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...
