Determination of the effective diffusion coefficient
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
The equation for drying kinetics is obtained, base on the analytical solution of the differential equation with a boundary condition in the form of the flux. This equation was initially developed by G. Efremov. In this ...
Concrete mix design for reconstruction of northwest breakwater in the Tripoli harbour - Libya
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
Reconstruction of Northwest breakwater in the Tripoli Harbour - Libya (about 4500 m long) required manufacture of various concrete elements (cubes and accropodes) in total amount of 550 000 m(3). Volumes of cubes were 6,3 ...
Mechanical properties of ultra high performance self compacting concrete with different mineral admixtures
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
Preparation and microstructure of ultra high performance concrete (UHPC) have been intensively analyzed In the last few years. The mechanical properties (compressive strength and flexural strength) were investigated under ...
Determination of recycled aggregate concrete degradation by resonance frequency analysis
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
The evaluation of the dynamic modulus of elasticity of twelve different concrete mix proportions as a function of the density and degradations due to freeze/thaw cycles is presented in this paper. Pore system and saturation ...
Toplotna svojstva glinenih proizvoda i energetska efikasnost zgrada / Clay products thermal properties and energy efficiency of buildings
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2011)
U radu se razmatraju toplotna svojstva glinenih proizvoda u termičkom omotaču zgrade sa aspekta principa energerske efikasnosti saglasno EPBD2, CEN/TR 15615 ('Umbrella document') i CPD 89/106/EEC.
Primena postupaka poroziranja opekarskih proizvoda sekundarnim sirovinama / Improving porosity of heavy clay bricks using secondary raw materials
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2011)
Uvažavajući zahteve održivog razvoja u ciglarskoj industriji poslednjih godina se sve više istražuje mogućnost upotrebe otpada u kompozitima na bazi gline, u cilju očuvanja prirodnih resursa, sirovina i energije. U ovom ...
Izbor optimalnog dodatnog materijala za reparaturno zavarivanje vratila turbine hidrocentrale na licu mesta / Selection of the optimal filler material for on-site repair welding of the turbine shaft at the hydropower plant
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2011)
Najznačajniji delovi hidroelektrana, vratila turbina izložena su tokom rada visokim naprezanjima, puzamju, zamoru i koroziji. Zbog toga je korisno preduprediti oštećenja tokom rada, povećati pouzdanost i produžiti radni ...
Engineering geological evaluation of the conditions for constructing a bridge and a tunnel in the zone of the old Petrovaradin Fortress, Serbia
(Springer, 2011)
The paper discusses the geotechnical conditions related to the construction of a new bridge over the Danube and a tunnel passing beneath the Petrovaradin Fortress at Novi Sad, Serbia. Analyses showed that both the bridge ...
