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 ...
Validation of energy-dispersive X-ray fluorescence procedure for determination of major and trace elements present in the cement based composites
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Adjustment and subsequent validation of energy-dispersive X-ray fluorescence (ED-XRF) method for cement based binders with addition of mineral raw materials (fly ash, zeolite and bentonite) was conducted. Eighteen chemical ...
Chemometric analysis of the influence of mechanical activation on the mica quality parameters
(Elsevier Sci Ltd, Oxford, 2015)
The differences in the set of the process parameters measured before and after mica mechanical activation and their influence on the grain size distribution related characteristics have been studied. The modification of ...
Discrete element model of particle transport and premixing action in modified screw conveyors
(Elsevier Science Bv, Amsterdam, 2018)
In this paper, five types of horizontal single-pitch screw conveyors with modified geometry, with three different lengths (400, 600 and 800 mm) were investigated for transport and auxiliary mixing action of two materials: ...
Effects of mechanical and thermal activation on pozzolanic activity of kaolin containing mica
(Elsevier Science Bv, Amsterdam, 2016)
Kaolin from a Serbian deposit, characterized by high content of impurities, such as mica and quartz, disordered kaolinite and high specific surface area, was subjected to thermal and mechanical activation on a large scale. ...
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 ...
Effect of LCF on behavior and microstructure of microalloyed HSLA steel and its simulated CGHAZ
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Numerous structural components made of high strength low-alloyed steels are often exposed to low-cycle fatigue loading during their exploitation life. In order to study the fatigue behavior of one grade of structural steels ...
Artificial fly ash based aggregates properties influence on lightweight concrete performances
(Elsevier Sci Ltd, Oxford, 2015)
The effect of the application of pelletized fly ash based aggregates obtained through different processing techniques on the behavior of lightweight concretes was analyzed. Experimental program implied production of four ...
What to expect from heavy clay?
(Elsevier Sci Ltd, Oxford, 2013)
The need of testing the quality of brickclay arises in all brick factories, with the opening of new deposits. The analyses are both time and economically consuming, so the aim of this study was to shorten the procedure ...
