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 ...
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 ...
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 ...

Microstructural analysis as the indicator for suitability of weld repairing of the heat resistant Cr - Ni steel
(Consejo Superior Investigaciones Cientificas-Csic, Madrid, 2010)
Metallurgical evaluation was performed on a fractured column tube of the reformer furnace in an ammonia plant. The tubes were manufactured from centrifugally cast heat resistant steel HK 40. Optical and scanning electron ...
Residual life estimation of a thermal power plant component: The high-pressure turbine housing case
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2009)
This study focuses on the estimation of residual life of damaged thermal power plant components. The high-pressure turbine housing was chosen as an example of thermal power plant component where, during the years of ...
Activated flux tig welding of stainless-steel pipes
