Characterisation of high-carbon steel surface welded layer
(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
In this paper microstructural and mechanical properties of high-carbon steel surface welded layer, obtained with self-shielded flux cored wire, are presented in the case of a standard rails and crossings. The testing results ...
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 ...
Effects of operation temperature on thermal expansion and main parameters of radial ball bearings
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
The research of influence of operation temperature on the thermal expansion and main parameters of radial ball bearings is presented in this paper. The main bearing parameters are identified in accordance with the increasing ...
Thermal, Ceramic and Technological Properties of Clays used in Production of Roofing Tiles - Principal Component Analysis
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
This research describes a study of 11 selected samples of brick clays applied in roofing tile production, by using simultaneous thermal analysis. Additionally, the laboratory-sized samples were prepared and fired (850-950 ...
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 ...
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 ...
Properties of composite cement with commercial and manufactured metakaolin
(Univ Osijek, Tech Fac, Slavonski Brod, 2013)
Metakaolin composite cements were prepared with 5 to 35 % replacement of ordinary Portland cement with metakaolin (MK), manufactured by thermal activation/calcination of domestic kaolin clay, and commercial matakaolin ...
Update of the procedure used for heavy clay dryer optimization
(Serban Solacolu Foundation, Bucurest, 2018)
The description of the moisture transfer in porous media during drying was the subject of many scientific studies. The unique drying theory was developed five years ago and has recently won a general recognition in the ...
