The Chemometric Study of Limestone Physico-chemical Properties and Thermal Behavior for Application in Construction Composites
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
The limestone, as an economically sustainable and easily available basic raw material, is frequently utilized in the building industry for resolving of the environmental protection issues. The limestone is incorporated in ...
Sintering of Fly Ash Based Composites with Zeolite and Bentonite Addition for Application in Construction Materials
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Due to pozzolanic characteristics, fly ash is commonly used as a cement replacement in construction composites. Addition of natural clays with sorption ability (i.e. zeolite and bentonite) in to the fly ash based construction ...
A Kinetic Study of Limestone Dry Micronization in an Ultra-Centrifugal Mill with Peripheral Comminuting Path
(Goller Verlag Gmbh, Baden Baden, 2017)
Because of its physico-mechanical and physico-chemical characteristics, fine-ground (i.e. micronized) limestone is widely applied in the production of new materials. Limestone can be used as a filler, coating and/or powder ...
Behaviour of nionikral-70 in low-cycle fatigue
(Institut za ispitivanje materijala, Beograd, 2017)
Experimental research on the behaviour of high-strength low-alloy steel ( HSLA)exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon =epsilon(min)/epsilon(max) ...
Analiza trenutnog stanja i ocena integriteta cevovoda na hidroelektrani Pirot / Analysis of current state and integrity evaluation of the pipeline at hydro power plant 'Pirot'
(Institut IMK "14. oktobar", Kruševac, 2017)
Hidroelektrana Pirot, koja je izgrađena 1990 godine, je akumulaciona elektrana derivacionog tipa, koja se sastoji od dva nadzemna vertikalna agregata sa Francis turbinama nominalne snage 41,5 MW, proizvedene u Češkoj ...
Optimization of bentonite clay mechano-chemical activation using artificial neural network modeling
(Elsevier Sci Ltd, Oxford, 2017)
The properties of seven montmorillonite-rich bentonites of different geological origin were investigated prior and subsequent to mechano-chemical processing in an ultra-centrifugal mill. The objective of the experiment was ...
A new method of coal excavation in the complex natural-geological conditions
(Institut za rudarstvo i metalurgiju, Bor, 2017)
In the underground coal mines in Serbia, nowadays, only the pillar methods of excavation excavations, which all affect the excavation economy. This paper presents the solution of a new excavation method foreseen for ...
The influence of tailings and cement type on durability properties of self-compacting concrete
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
In order to examine the differences in chemical composition and the possibility of using mine tailings in mortar and concrete production, samples were taken from the landfill and directly from the production. Tailings test ...
Određivanje in-situ koeficijenta trenja i imperfekcije kablova za prednaprezanje / Determination of the in situ coefficient of friction and imperfection of prestressing cables
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
Prednaprezanjem konstruktivnih elemenata omogućava se povećavanje raspona armiranobetonskih konstrukcija. Pri projektovanju i dimenzionisanju prednapregnutih armiranobetonskih konstrukcija, neophodno je poznavanje, odnosno ...
Dynamics of train composition as a discrete non-homogeneous chain system
(Abstracts of 14th International conference Dynamical Systems - Theory and Applications, 2017)
The longitudinal train dynamics which included movement and oscillations of coupled railway vehicles only in the direction of the track (longitudinal) is analyzed. The one direction motion of the train, ...
