Greške na elementima od aluminijum-magnezijum legure - uticaj uključaka / The flaws of aluminium-magnesium alloy elements: Influence of inclusions
(Institut za rudarstvo i metalurgiju, Bor, 2014)
Rezultati ispitivanja uticaja uklanjanja gasa iz tečnog metala na kvalitet livenih elemenata od aluminijum-magnezijum legure, a na bazi recikliranih materijala su dati ovom radu. Dobijeni rezultati praktično definišu ...
Synthesis and characterization of new refractory coatings based on talc, cordierite, zircon and mullite fillers for lost foam casting process
(Polska Akad Nauk, Polish Acad Sciences, Inst Metall & Mater Sci Pas, Warszawa, 2014)
Refractory coatings based on different refractory fillers (talc, cordierite, zircon and mullite) for application in Lost Foam casting process were investigated. Design and optimization of the coatings composition with ...
The influence of silica fume and curing regime on some properties of concrete
(Revista Romana de Materiale/ Romanian Journal of Materials, 2014)
The investigation of posibilities of concrete structure modification by silica fume to improve concrete properties was presented in this report. Percentage of silica fume in regard to cement varied between 0% and 20%. ...
Mechanically activated coal ash as refractory bauxite shotcrete microfiller: Thermal interactions mechanism investigation
(Elsevier Sci Ltd, Oxford, 2014)
A growing demand for refractory castables with advanced properties has given rise to a continuous technological evolution and highlighted the necessity for secondary raw materials reapplication even in refractory industry. ...
Investigation of high temperature behavior and sintering mechanism of fly ash based concretes
(Procema SA, 2014)
Four types of refractory concretes were studied at various temperatures ranging from ambient to adopted maximal 1400 degrees C. The concretes had same matrix composition: K concretes were based on corundum aggregate; B ...
Determination of the moisture diffusivity coefficient and mathematical modeling of drying
(Elsevier Science Sa, Lausanne, 2014)
Drying plays an important role in the production of clay tiles. In the present article, drying process is analyzed taking experimental data for several masonry clays obtained from different clay tile manufacturers and ...
