Procena čvrstoće betona pri pritisku, korišćenjem različitih funkcija zrelosti betona - primer iz prakse / Assessment of concrete compressive strength using different maturity functions: Case study
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
Čvrstoća pri pritisku jeste svojstvo koje je veoma značajno u građevinarstvu, te postoji izražena potreba da se razviju metode za praćenje prirasta čvrstoće pri pritisku betona u konstrukciji. Prema zakonskim propisima ...
Possibility of using bottom ash in precast concrete products
(Croatian Soc Civil Engineers-Hsgi, Zagreb, 2018)
Chemical, physical and mechanical properties of bottom ash from two thermal power plants were analysed in order to evaluate the quality of bottom ash and to determine the possibility of its use in composite materials. It ...
Integrity assessment of vital beam components that enable conjoint operation of two bridge cranes
(Institut za ispitivanje materijala, Beograd, 2018)
Vital components of the beam that enable conjoint operation of two bridge cranes are braces and threaded spindle. The beam connects two bridge cranes with overall lifting capacity of 500 t (2 × 250 t) and enables their ...
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 ...
Discrete element model of particle transport and premixing action in modified screw conveyors
(Elsevier Science Bv, Amsterdam, 2018)
In this paper, five types of horizontal single-pitch screw conveyors with modified geometry, with three different lengths (400, 600 and 800 mm) were investigated for transport and auxiliary mixing action of two materials: ...
Analiza povredljivosti i pouzdanosti interakcije tlo -šip -stub most / Fragility and reliability analyses of soil -pile -bridge pier interaction
(Univerzitet u Nišu, Niš, 2018)
U radu je prikazana procedura evaluacije seizmičkih performansi interakcije šip-tlo inkrementalnom nelinearnom dinamičkom analizom (INDA -Incremental Nonlinear Dynamic Analysis). Ulazni signal u sistemu je tretiran preko ...
Determination of critical size of corrosion pit on mechanical elements in hydro power plants
(Udruženje intelektualaca za razvoj nauke u Srbiji, Novi Sad, 2018)
Researchers in the field of fracture mechanics, predominantly developing appropriate solution algorithms for problems of solid bodies with cracks. Problems in mechanics generally, related with fracture and fatigue for solid ...
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 ...
Microstructure and Phase Composition Of Steatite Ceramics Sintered by Traditional and Spark Plasma Sintering
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
The influence of the sintering method on the mineral phase transformations and development of the crystalline microstructure of steatite ceramics was investigated. The steatite samples were fabricated from talc and bentonite ...
Methodological procedure for selection the type and construction of self-propelled hydraulic support for coal excavation on the example of the coal deposit 'Poljana'
(Institut za rudarstvo i metalurgiju, Bor, 2018)
For the application of a wide forehead method, decisive is an assessment, respectively, selection of the type and construction of self-propelled hydraulic support, both for horizontal and vertical excavation concentrations. ...
