Effect of changes in matric suction on slope stability in natural unsaturated soil
(ICE Publishing, 2015)
Stability analyses were performed for a real engineering-geological cross-section of unsaturated Quaternary silt sediments. Unsaturated shear strength is a function of the two stress variables: net normal stress and matric ...
Istraživanje sadržaja teških metala u opekarskim proizvodima na bazi glina i sekundarnih sirovina / Heavy metals content in brick products based on clay and secondary raw materials
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2011)
Teški metali spadaju u najopasnije zagađujuće supstance životne sredine. Usled razvoja industrije dolazi do nekontrolisane emisije metala u atmosferu i hidorsferu, kao i kasnije akumulacije u sedimentima i zemljištu. Cilj ...
Comparative analysis of process parameters of talc mechanical activation in centrifugal and attrition mill
(Oficyna Wydawnicza Politechniki Wroclawskiej, Wroclaw, 2014)
The efficiency of talc mechanical activation by means of two different mechano-activators centrifugal and attrition mill is investigated in this study and the comparative analysis of the characteristics of obtained talc ...
Synthesis, characterization and application of the filler based on corundum for obtaining the ceramic coats in foundry
(Editura Stiintifica Fmr, Bucharest, 2012)
In this work, a possibility to develop new ceramic coats based corundum for casting applications has been examined. Optimization of coating composition with controlled rheological properties was attained by applying different ...
Determination of apparent porosity level of refractory concrete using ultrasonic pulse velocity technique and image analysis
(American Ceramic Society, 2011)
Aim of this paper is to establish the correlation between sintering process, porosity and important thermo-mechanical property of refractory concrete, i.e. creep. Creep deformation was investigated according to standard ...
The failures of a supporting structure of a coal-reloading bridge and methodological approach to recovery of the damages
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
In present paper, methodological approach to the analysis of the failures and recovery of the damages has been presented on an example of fracture and damage of a structure of the reloading bridge. The approach presented ...
Natural, modified and saturated zeolites as additives in Portland cement
(Bauverlag Bv Gmbh, Gutersloh, 2014)
Optimization of bentonite clay mechano-chemical activation using artificial neural network modeling
(Elsevier Sci Ltd, Oxford, 2017)
The properties of seven montmorillonite-rich bentonites of different geological origin were investigated prior and subsequent to mechano-chemical processing in an ultra-centrifugal mill. The objective of the experiment was ...
Optimization of drying through analytical modeling: clays as bonding agents in refractory materials
(Elsevier Sci Ltd, Oxford, 2016)
The objective of this study was to investigate the clay drying as a unit operation in the refractory materials processing. Two clays that varied in chemical and mineralogical compositions were experimentally tested in a ...
Some properties of concrete based on recycled bricks
(Revista Romana de Materiale/ Romanian Journal of Materials, 2010)
By using crushed brick as aggregate, the structure of concrete can be effectively modeled and materials with very different physical-mechanical characteristics can be obtained. Determination of the influence of polymer ...
