Bitne karakteristike građevinskih proizvoda i interpretativni dokumenti proistekli iz direktive CPD 89/106/EEC i uredbe 305/2011 / The essential performances of construction materials and interpretation documents arising from directive 89/106/EEC and regulation 305/2011
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2011)
Direktiva CPD 89/106/EEC i Uredbe P6-TA (2009)0320 i 305/2011 regulišu oblast usaglašenosti plasmana građevinskih konstrukcionih materijala na teritoriji zemalja članica evropske zajednice. Da bi se to postiglo, bilo je ...
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 ...
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 ...
Cracking resistance of AlMg4.5Mn alloy TIG welded joints
(Institut za ispitivanje materijala, Beograd, 2011)
In this paper the AlMg4.5Mn TIG welded joints have been tested in order to investigate their cracking resistance. Testing plates, size of 500×250×12 mm, are welded by TIG procedure in a horizontal-vertical position. Various ...
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 ...
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 ...
