Buckling resistance of stainless steel angle column
(Union of Croatian Civil Engineers and Technicians, 2019)
A numerical study of compressive capacities of stainless steel angle columns is presented in the paper in order to assess the design procedures presented in Eurocode 3. The study focuses on pin-ended hot-rolled equal angle ...
Assessment of Efficiency of Rare Earth Elements Recovery from Lignite Coal Combustion Ash via Five-Stage Extraction
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
Rare earth elements (REE) are frequently referred to as ingredients for enhancements in modem industry, as they are extensively applied in many industrial branches due to their accented electro-magnetic and optical properties. ...
Study on the addition effect of metakaolin and mechanically activated kaolin on cement strength and microstructure under different curing conditions
(Elsevier Sci Ltd, Oxford, 2017)
The effects of thermally (MK) or mechanically activated kaolin (AK) on the compressive strength of mortars and microstructure of pastes were investigated. Mortar mixtures, in which 10%, 20% and 30% of ordinary Portland ...
Mechanically activated coal ash as refractory bauxite shotcrete microfiller: Thermal interactions mechanism investigation
(Elsevier Sci Ltd, Oxford, 2014)
A growing demand for refractory castables with advanced properties has given rise to a continuous technological evolution and highlighted the necessity for secondary raw materials reapplication even in refractory industry. ...

(Elsevier Sci Ltd, Oxford, 2016)
The development of building materials with improved characteristics and their application for increasing structure durability and sustainability is one of the goals in construction sector. The main objective of this paper ...
Indicators of HSLA steel behavior under low cycle fatigue loading
(Elsevier Science Bv, Amsterdam, 2016)
In present paper, the experimental research of 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 = ...
Microstructure analysis and crack detection in turbine blades after prolonged exposure in plant
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
Turbine blades are one of the most important machine parts in every power generator. Corrosion and/or erosion attack on blades are also available in moisture atmosphere, because the wet water vapour is an usual working ...
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 ...
Review of results of interlaboratory comparisons of national accredited laboratorys in the free field noise level measurements
(IEEE, NEW YORK, 2015)
Interlaboratory comparisons in the field of enviromental noise level measurements were organized by IMS Institute in Belgrade in August this year as a part of the standard noise monitoring according to of the method given ...
Experimental and Discrete Element Model Investigation of Limestone Aggregate Blending Process in Vertical Static and/or Conveyor Mixer for Application in the Concrete Mixture
(MDPI, Basel, 2021)
The numerical model of the granular flow within an aggregate mixture, conducted in the vertical static and/or the conveyor blender, was explored using the discrete element method (DEM) approach. The blending quality of ...
