Influence of increased temperature on clay fast drying process
(Revista Romana de Materiale/ Romanian Journal of Materials, 2009)
In this paper are presented testing results during process of fast drying at conditions of increased temperature. Three different masonry raw materials were examined using recircular laboratory dryer with air recirculation. ...
Research of possibilities for use domestic kaolin clays for production of metakaolin
(Savez hemijskih inženjera, Beograd, 2009)
Environmental concerns coming from the high energy consumption and CO2 emission associated with cement production have brought about pressures to reduce cement consumption through the use of new materials which can be ...
Uticaj parametara EPP postupka zavarivanja na mehaničke osobine spiralno zavarenih cevi od čelika API X60 / Influence of SA procedure welding parameters on mechanical properties spiral welded steel tubes API X60
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2009)
Izbor čelika, dimenzija i načina proizvodnje zavarenih cevi je deo procesa konstruisanja, jer je u uskoj vezi sa funkcijom cevi kao konstrukcijske celine u određenim uslovima eksploatacije za predviđeni vek trajanja. ...
Correlation among sintering process, porosity, and creep deformation of refractory concrete
(Springer, New York, 2009)
The aim of this paper is to establish the correlation among sintering process, porosity, and important thermo-mechanical property of refractory concrete, i.e., creep. Creep deformation was investigated according to the ...
Quantitative Formulation of Mechanism of Sintering Process during Creep Deformation of Refractory Concretes
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
This paper is concerned with quantitative formulation of the mechanism of the sintering process during secondary state creep deformation of refractory concretes. Investigated concretes varied in, both, chemical and ...
New possibilities of application of cordierite ceramics
(Silicates Industriels, 2009)
Cordierite ceramics have an important role in modem technology. Standard raw materials, kaolinite, tale, magnesia, alumina were used in synthesis of cordierite ceramics. Composition of cordierite ceramics is 2MgO-2Al 2O ...
Hronologija gubitka integriteta konstrukcija zbog grešaka izrade zavarenih konstrukcija / Chronology of lost structural integrity initiated from manufacturing defects in welded structures
(Institut za ispitivanje materijala, Beograd, 2009)
U različitim vremenskim periodima dolazilo je do gubitka integriteta zavarenih konstrukcija zbog razvoja proizvodnih grešaka zavarenog spoja. Mehanizmi otkaza su bili različiti i uvek su predstavljali novo iskustvo, koje ...
