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 ...
Identification of low cycle fatigue parameters of high strength low-alloy (HSLA) steel at room temperature
(Croatian Metallurgical Soc, Zagreb, 2014)
Low cycle fatigue test was performed in ambient atmosphere at room temperature. cycle loading of material, in case of High strength low-alloy steel, entails modifications of its properties and in this paper is therefore ...
Need to Improve the Natural Aggregate Resources Supply in the City of Belgrade (Serbia)
(Berg Fac Technical Univ Kosice, Kosice, 2016)
The City of Belgrade is the largest market for aggregates in Serbia but the production of natural aggregates is rather small, around five percent of total consumption. This reflects the geology of the City of Belgrade ...
Pregled savremenih seizmičkih analiza i načina uvođenja prigušenja u njima / An overview of modern seismic analyses with different ways of damping introduction
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
Autori rada su, na osnovu analize velikog broja naučnih radova, dali prikaz sopstvene originalne sistematizacije seizmičkih analiza konstrukcija, a veliki deo njih je razvijen u poslednje dve decenije. Seizmičke analize ...
Evaluation of air content on concrete compressive strength with classical approach and neural networks
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2012)
Mnogi parametri utiču na karakteristike svežeg i očvrslog betona. Jedan od najvažnijih svakako jeste poroznost betona. Poroznost svežeg betona meri se količinom uvučenog vazduha. Uticaj uvučenog vazduha na beton i njegovu ...
Procena čvrstoće pri pritisku betona sa prirodnim i recikliranim agregatom / The estimation of compressive strength of normal and recycled aggregate concrete
(Univerzitet u Nišu, Niš, 2011)
Procena čvrstoće pri pritisku se postavlja kao važan zadatak proizvođačima betona, naročito pri projektovanju betonskih mešavina i obezbeđenju zahtevanog kvaliteta proizvedenog betona. U radu je prikazano poređenje ...
Characterization of New Structure for Silicon Carbide X-Ray Detector by Method Monte Carlo
(Polish Acad Sciences Inst Physics, Warsaw, 2011)
This work presents a characterization of radiation absorption properties of silicon carbide (SiC) as semiconductor for the realization of detectors for X-rays. SiC detectors can potentially reach superior performance with ...
Investigation of the mortar and concrete resistance in aggressive solutions
(Univ Osijek, Tech Fac, Slavonski Brod, 2014)
Testing the influence of two aggressive solutions - sulphate and nitrate on mortar and concrete was presented in this paper. Experimental work included testing of mortar prisms with 5 % special admixture. Also, four types ...
Procena opasnosti od likvefakcije analizom in situ CPT opita i indeksnih pokazatelja tla / Assessment of liquefaction hazard by in situ CPT test analysis and indexing indicator of soil
(Srpsko društvo za puteve VIA-VITA, Beograd, 2011)
Procena seizmičkog ponašanja zasićenog tla u uslovima zemljotresa zasniva se na geotehničkim istraživanjima i ispitivanjima i poznavanju seizmičkog režima izučavanog područja. Likvefakcija se obično pripisuje rastresitim, ...
Tehnologija zavarivanja polimetilmetakrilata (PMMA) / Polymethylmethacrylate (PMMA) welding technology
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2010)
Polimetilmetakrilat (PMMA), zbog svojih karakteristika, pre svega transparentnosti i relativno male gustine, predstavlja danas vrlo atraktivan materijal u inženjerstvu. Zbog toga, istražuju se nove mogućnosti spajanja ovog ...
