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 ...
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 ...
Drying kinetic simulation of clay tiles made from the raw material having less clay fraction
(Trans Tech Publications Ltd, 2014)
In order to describe the internal moisture rate and to take all different mechanisms of moisture movement into account, it is suitable to use effective diffusivity as a measure of moisture rate, irrespectively of the ...
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, ...
Influence of nanoparticles on the strength of ultra-high performance concrete
(Elsevier, 2018)
Ultra-high performance concrete (UHPC) is a modern composite material with extremely good mechanical characteristics. The application of nanoparticles in concrete is one of the possibilities for improving its properties. ...
Opekarske gline iz Srbije - primena u proizvodnji grube keramike / Serbian heavy clays behavior: Application in rough ceramics
(Savez hemijskih inženjera, Beograd, 2013)
Gline i glineni minerali se, usled mnogih specifičnih osobina pre i nakon pečenja, decenijama koriste kao osnovni materijali za proizvodnju grube keramike. Proučavanje i utvrđivanje mineralnih faza koje su prisutne u ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...
Otpornost materijala na bazi metalurškog cementa na dejstvo kiselina / Resistance of CEM III/B based materials to acid attack
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
Cementni materijali u poljoprivrednim i drugim industrijskim objektima izloženi su dejstvu kiselina. Zbog toga vek konstrukcija zavisi od trajnosti maltera ili betonskih elemenata u agresivnoj sredini. U radu je predstavljena ...
Response surface method as a tool for heavy clay firing process optimization: Roofing tiles
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2012)
Heavy clay samples collected in close vicinity of Toplička Mala Plana, Serbia, were surveyed to examine their possible use in heavy clay industry. The representative raw material, which contained the lowest content of clay ...
Osnovni pojmovi kod postupka zavarivanja trenjem sa mešanjem prema AWS D17.3/D17.3M:2010 i ISO 25239-1: 2011 / Basic terms in friction stir welding according to AWS D17.3/D17.3M:2010 i ISO 25239-1: 2011
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2012)
Zavarivanje trenjem sa mešanjem - ZTM (eng. Friction Stir Welding - FSW) je relativno mlad postupak zavarivanja u čvrstom stanju nastao na Institutu za zavarivanje (TWI) u Londonu, krajem 1991. godine. Prva primena ZTM ...
