Assessment of Efficiency of Rare Earth Elements Recovery from Lignite Coal Combustion Ash via Five-Stage Extraction
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
Rare earth elements (REE) are frequently referred to as ingredients for enhancements in modem industry, as they are extensively applied in many industrial branches due to their accented electro-magnetic and optical properties. ...
An Artificial Neural Network-based Prediction Model for Utilization of Coal Ash in Production of Fired Clay Bricks: A review
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
This study analyzed the last 20 years' data available on power plant coal ashes used in clay brick production. The statistical analysis has been carried out for a total of 302 cases based on the relevant parameters reported ...
Potential pathway for recycling of the paper mill sludge compost for brick making
(Elsevier Sci Ltd, Oxford, 2021)
This study's focus was to develop a potential pathway for recycling of the paper mill sludge compost (PMSC) in brick making. Composting reduces the paper mill sludge (PMS) moisture content considerably and shredding becomes ...
Cavitation Properties of Rendering Mortars with Micro Silica Addition
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
Micro-silica is a highly efficient mineral additive whose role is reflected in improvements of microstructure packing, strength and durability of non-shaped composite building materials such as concrete and mortar. A ...
Model of Probabilistic Analysis of Pile Capacity Based on the Extrapolation of Load-Settlement Curves
(Springer, New York, 2020)
This paper formulates a mathematical model using the extrapolation of load-settlement curves with a rational function for analyzing the capacity of piles obtained from the static load test (SLT). In preliminary analyses, ...
Performances of Vermiculite and Perlite Based Thermal Insulation Lightweight Concretes
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2020)
This experimental study was conducted with an aim to investigate the effect of the elevated temperature on the mineral phase composition, microstructure and mechanical properties of the thermal insulation lightweight ...
Optimization of adobe clay bricks based on the raw material properties (mathematical analysis)
(Elsevier Sci Ltd, Oxford, 2020)
This research studies the effects of composition and granulometry analysis of 139 heavy clays on the important characteristics of wet and adobe clay bricks. ANN models were obtained with high prediction accuracy in training ...
Linearno toplotno širenje građevinskog kamena poreklom iz plutonskih magmatskih kompleksa Eksterne vardarske zone Srbije / Linear thermal expansion of the building stone from plutonic massifs of the Vardar zone of Serbia
(Savez inženjera i tehničara Srbije, Beograd, 2020)
Toplotna svojstva građevinskog kamena koji se koristi za oblaganje vertikalnih i horizontalnih površina građevinskih objekata, naročito u eksterijeru, imaju veliki značaj za stabilnost i vek trajanja, ali i estetska svojstva ...
Unapređenje tehnologije aluminotermijskog zavarivanja železničkih šina različitog poprečnog preseka / Improvement of at-welding technology of railway rails with different cross sections
(Savez inženjera i tehničara Srbije, Beograd, 2021)
U radu je prikazana nova tehnologija aluminotermijskog zavarivanja (AT) prelaznih šina 49E1 na 60E1(EN 13674-1:2005.), oslonjena na potpuno nove materijale. Ona se odnosi na pešćane kalupe kod kojih su oblik i dimenzije ...
Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer India, New Delhi, 2021)
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
