Sintering of Fly Ash Based Composites with Zeolite and Bentonite Addition for Application in Construction Materials
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Due to pozzolanic characteristics, fly ash is commonly used as a cement replacement in construction composites. Addition of natural clays with sorption ability (i.e. zeolite and bentonite) in to the fly ash based construction ...
A Kinetic Study of Limestone Dry Micronization in an Ultra-Centrifugal Mill with Peripheral Comminuting Path
(Goller Verlag Gmbh, Baden Baden, 2017)
Because of its physico-mechanical and physico-chemical characteristics, fine-ground (i.e. micronized) limestone is widely applied in the production of new materials. Limestone can be used as a filler, coating and/or powder ...
Possibility of using bottom ash in precast concrete products
(Croatian Soc Civil Engineers-Hsgi, Zagreb, 2018)
Chemical, physical and mechanical properties of bottom ash from two thermal power plants were analysed in order to evaluate the quality of bottom ash and to determine the possibility of its use in composite materials. It ...
Durability of concrete with different types of cement
(Procema SA, 2016)
Adequate measures must be taken during the determination of the concrete composition for ensuring the durability of concrete exposed to an aggressive environment. The influence of the cement type on the freeze/thaw resistance ...
Establishing a method for determination of effective diffusion coefficiente
(ModTech Publishing House, 2011)
The aim of this paper is to calculate the effective diffusion coefficient for typical masonry clay on the base of experimentally recorded drying curves. Two computer programs for calculation of diffusion coefficient, which ...
Integrated LCA and LCCA network level pavement maintenance model
(CRC Press/Balkema, 2019)
Pavement management systems tend to lead to sound decision making regarding the optimal maintenance strategy which is, in most cases, based on the achievement of minimal total society costs which are defined as the sum of ...
Predviđanje optimalnih parametara interventnog reparaturnog zavarivanja čelika 13CrMo4-5 analitičkim metodama / Optimal parameters estimation by the analytical methods for the emergency repair welding of the 13CrMo4-5 steel
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2010)
Već dugi niz godina se čelik 13CrMo4-5 (~Č7400) primenjuje za izradu delova termoenergetskih postrojenja kao što su elementi kotlova i cevi. Ovaj čelik pripada grupi uslovno zavarljivih čelika, koji mogu uspešno da se ...
Activated carbons obtained by pyrolyzing of resorcinol formaldehyde gels
(University of East Sarajevo, Faculty of Technology, 2010)
Activated carbon is used in different industrial domains due to highly developed specific surface area and its specific chemistry. Properties of activated carbons obtained by pyrolyzing formaldehyde gels are presented in ...
Determination of the apparent porosity level of refractory concrete during a sintering process using an ultrasonic pulse velocity technique and image analysis
(Savez hemijskih inženjera, Beograd, 2010)
Concrete which undergoes a thermal treatment before (pre-casted concrete blocks) and during (concrete embedded in-situ) its life-service can be applied in plants operating at high temperature and as thermal insulation. ...
Energy conversion in phosphate ore grain mixture activated via ultra-centrifugal mill
(Elsevier, Amsterdam, 2015)
The aim of this investigation was to establish the optimal processing parameters of the comminuted phosphate grain mixture mechanical treatment by monitoring and evaluating the activated product characteristics. An ...
