The effect of shielding gas on the toughness of ALMg4.5Mn weld metals made by GMAW
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2011)
The effect of MIG/MAG shielding gas on the toughness of aluminium alloy AlMg4.5Mn weld metal has been analysed using the instrumented Charpy pendulum for standard toughness testing. The MIG/MAG welding was performed in the ...
Istraživanje sadržaja teških metala u opekarskim proizvodima na bazi glina i sekundarnih sirovina / Heavy metals content in brick products based on clay and secondary raw materials
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2011)
Teški metali spadaju u najopasnije zagađujuće supstance životne sredine. Usled razvoja industrije dolazi do nekontrolisane emisije metala u atmosferu i hidorsferu, kao i kasnije akumulacije u sedimentima i zemljištu. Cilj ...

U radu je dat uporedni prikaz eksperimentalno utvrđenih rezultata svojstava opekarske sirovine, koja je bila pripremljena standardnim postupkom prerade i postupkom mehaničke aktivacije. Uobičajeni standardni postupak prerade ...
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 ...
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 ...
Određivanje koeficijenta prenosa toplote prilikom sušenja opekarskih proizvoda / Determination of the heat transfer coefficient during drying of heavy clay products
