The new tool insert design for prevention the rotation of horizontal wire during shear testing of welded fabric
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Many new requirements in the field of experimental mechanics, like testing of metallic materials, emphasize traceability and accuracy of test results as the end goal. These requirements have energy efficiency context too, ...
Ex post analysis of road projects: resilience to crisis
(Editorial Board EJTIR, 2018)
This investigation aimed to reveal a mechanism of how different road projects' settings respond to macro-economic crisis. Qualitative and quantitative analyses were performed over a sample of 31 European road projects, in ...
Implementation of Preventive Maintenance in Network-Level Optimization Case Study of the Serbian Low-Volume Road Network
(Natl Acad Sciences, Washington, 2015)
Application of appropriate preventive maintenance treatments, at the right time, extends the service life of pavements, resulting in benefits to road users through increased ride comfort and safety and to road agencies ...
Network-Level Pavement Management Case of Serbian Low-Volume Roads
(Natl Acad Sciences, Washington, 2011)
This paper presents the application of the World Bank's Road Network Evaluation Tools (RONET) model to strategic network-level analysis of the Serbian state low-volume road (LVR) network. This network condition deteriorated ...
Chemometric assessment of mechano-chemically activated zeolites for application in the construction composites
(Elsevier Sci Ltd, Oxford, 2017)
Natural zeolites of clinoptilolite type from seven deposits were submitted to mechano-chemical activation in a Retsch ultra -centrifugal mill. The zeolite types and activation parameters were altered during the experiment ...
The effect of alternations in mineral additives (zeolite, bentonite, fly ash) on physico-chemical behavior of Portland cement based binders
(Elsevier Sci Ltd, Oxford, 2018)
Instrumental analyses accompanied by analytical modeling tools were employed to assess physico-chemical changes induced by variations in chemical composition of cementitious composites, i.e. mortar binders. Coal combustion ...
Chemometric Analysis of Alternations in Coal Ash Quality Induced by Application of Different Mechano-chemical Processing Parameters
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
The coal fly ash mechano-chemical activation conducted via high energy ultra-centrifugal mill was optimized using mathematical and statistical tools. The aim of the investigation was to accent the merits of alternations ...
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 ...
Analiza uticaja sučeono zavarenih spojeva na nosivost konstrukcije rezervoara / Analysis of the effects of butt welded joints on a carrying capacity of a structure tank
(Inženjersko društvo za koroziju, Beograd, 2017)
U radu je posle proračuna metodom konačnih elemenata (MKE) analizirana raspodela napona na modelu dela oplate rezervoara pod pritiskom bez zavarenih spojeva (ZS), sa obimnim ZS, podužnim ZS i ukrsnim mestom ZS. Takođe, u ...
