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 ...
Determination of the optimal drying condition during drying of green masonry products
(ModTech Publishing House, 2012)
Explanation of the drying process is reduced to the establishment of a series theoretical and empirical drying models. Complex processes of simultaneous mass and energy transfer, which are often non-stationary and the ...
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 ...
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 ...
State Analysis and Integrity of Welded Structures of the Upper Ring of the Turbine Runner Guide Vane Apparatus of Hydroelectric Generating Set A6 on Hydro Power Plant Djerdap 1
(Trans Tech Publications Ltd, Durnten-Zurich, 2013)
During the refurbishment of the hydroelectric generating set A6 on HPP "Djerdap 1", for the state analysis and assessment of the level and causes of degradation of the structure of the vertical Kaplan turbine runner guide ...
Prediction model for the cost of road rehabilitation and reconstruction works
(Univ Zagreb, Fac Civil Engineering, Zagreb, 2012)
Maintenance of existing road network represents a challenge for public road authorities who seek a balance between available budgets and the need for maintaining level of service at a satisfactory level on existing road ...
Drying Process Modelling for Heavy Clay Products Using a New Thin Layer Drying Model
(Trans Tech Publications Ltd, Stafa-Zurich, 2013)
Drying results, determined on samples made of masonry clay from the locality "Banatski Karlovac", are presented in this study. Experimental investigations were carried out in a laboratory recirculation dryer in which drying ...
Drying simulation of shrinkable clay tiles using variable diffusivity model
(Trans Tech Publications Ltd, Stafa-Zurich, 2014)
This paper represents the upgrade of our previous study in which we have presented a model for simulation of the drying kinetic and estimation of the effective moisture diffusivity of clay tiles using a constant diffusivity ...
Linings based chromite for application in foundry
(ModTech Publishing House, 2012)
In this work, a possibility to develop new chromite-based refractory linings for casting applications has been examined. Lining composition optimization with the controlled reologic properties was achieved by applying ...
