Analytical modeling of activation procedure applied in alpha-alumina thermo-mechanical synthesis
(Elsevier Sci Ltd, Oxford, 2015)
The impact of the mechanical processing parameters on the alumina grain-size distribution affiliated characteristics and on the gamma to alpha phase transformation rate was investigated. The moderation in the alumina samples ...
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 ...
The characterization and pollution status of the surface sediment in the Boka Kotorska Bay, Montenegro
(Springer Heidelberg, Heidelberg, 2021)
Surface sediments collected from twelve stations in the Boka Kotorska Bay were analyzed for the level and distribution of twenty-six elements and ten oxides, grain sizes, organic matter, and carbonate content. Potentially ...

Dehydration investigations of a refractory concrete using DTA method
(Springer, Dordrecht, 2012)
The base mix refractory concrete is corundum-based, containing corundum as refractory aggregate and CAC as hydraulic binder, with a spinel as an additive. The authors investigated the dehydration reactions which occur from ...
Water retention parameters and sediment dispersivity of the Zemun loess plateau (Belgrade, Serbia)
(Publ House Bulgarian Acad Sci, Sofia, 2019)
The paper presents the results of recent investigations of the Zemun Loess Plateau, which focused on unsaturated and dispersive loess soil. Soil water retention curves, SWRCs, were determined experimentally, using a pressure ...
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. ...
