Optimization of the production process through response surface method: Bricks made of loess
(Elsevier Sci Ltd, Oxford, 2013)
Loess clays are commonly used to produce bricks. Heavy clays, taken at location near Zrenjanin, Serbia, are used as a representative raw material in this study. The sample, containing about 28% of clay sized particles, is ...
Veza između mikrostrukture, faznog sastava i mehaničkih svojstava termo-izolacionih veziva na bazi otpadnog materijala / Correlation between microstructure, phase composition and mechanical properties of thermo-insulation bonding agents based on waste material
(Univerzitet u Nišu, Niš, 2012)
Konstrukcioni kompoziti - termo-izolaciona i/ili visoko-temperaturna veziva u kojima je leteći pepeo, kao potencijalno štetna materija za okolinu, kombinovan sa običnim i vatrostalnim cementom predstavlja jednu sasvim novu ...
Effect of LCF on behavior and microstructure of microalloyed HSLA steel and its simulated CGHAZ
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Numerous structural components made of high strength low-alloyed steels are often exposed to low-cycle fatigue loading during their exploitation life. In order to study the fatigue behavior of one grade of structural steels ...
Effect of absorption on active pressure in floury soil
(Pleiades Publishing Inc, Moscow, 2015)
Retaining walls are often built in unsaturated soil at shallow depth above groundwater level. It is critical to define active pressure in unsaturated soil for designing retaining walls, based on the expanded theory of ...
Application of Results of Nondestructive Testing Methods in the Investigation of Microstructure of Refractory Concretes
(ASCE - American Society of Civil Engineers, 2010)
The aim of this investigation is to establish the correlation between concrete porosity, compressive mechanical strength, and microstructure using the results of nondestructive testing methods, i.e., ultrasonic pulse ...
Low cycle fatigue of weldments produced of a high strength low alloyed steel
(Elsevier Science Bv, Amsterdam, 2014)
A quenched and tempered high strength low alloy steel NIONIKRAL 70 for producing welded pressure vessels, where high resistance to fatigue crack propagation and high tolerance of damage are of high importance, has been ...
Compressive Strength Improvements of Cement-Based Composites Achieved with Additional Milling of Metakaolin
(Springer, Dordrecht, 2018)
Kaolin from a Serbian deposit, having a high content of mica and quartz, disordered kaolinite and a high specific surface area, was used to prepare metakaolin (MK). The calcination at temperatures of 700 degrees C or 750 ...
Određivanje efektivnog koeficijenta difuzije prilikom sušenja uzoraka od gline / Calculation of the effective diffusion coefficient during the drying of clay samples
(Srpsko hemijsko društvo, Beograd, 2012)
Cilj ovog rada je da se na primeru dve opekarske gline sa različitih lokaliteta odredi efektivni koeficijenat difuzije na osnovu eksperimentalno snimljenih krivih sušenja. Razvijen je metod i napravljena su dva kompjuterska ...
Properties of the Cement-Based Composites with High Content of Metakaolin
(Springer, Dordrecht, 2018)
Environmental concerns and sustainable development require increased replacement of cement. Most of previous studies have shown that the compressive strength of cement-based composites is maximized with a 20% content of ...
Influence of modifying methods on quality of eutectic and hypereutectic silumine for diesel engine pistons
(Maney Publishing, Leeds, 2013)
The results of the investigation of the influence of different modifiers (sodium, phosphorus, antimony and strontium) on the quality of AlSi12CuMgNi and AlSi18CuMgNi alloys, which are used for the production of pistons, ...
