J-integral Analysis of the Simulated Heat-affected Zone of the Elevated-temperature Martensitic Steel
(Springer, New York, 2021)
Due to its superior strength at high temperatures P/T91 steel is often applied in the chemical, petrochemical and fossil-fired power generation industries. The high strength is achieved by a suitable martensitic microstructure ...
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. ...
Application of Paris' Law Under Variable Loading
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2022)
The most important characteristics for service safety of welded joints are those describing crack initiation and growth caused by variable loading. Crack initiation and growth caused by variable loading is the subject of ...
Experimental and Discrete Element Model Investigation of Limestone Aggregate Blending Process in Vertical Static and/or Conveyor Mixer for Application in the Concrete Mixture
(MDPI, Basel, 2021)
The numerical model of the granular flow within an aggregate mixture, conducted in the vertical static and/or the conveyor blender, was explored using the discrete element method (DEM) approach. The blending quality of ...
Prediction model based on artificial neural network for pyrophyllite mechano-chemical activation as an integral step in production of cement binders
(Elsevier Sci Ltd, Oxford, 2020)
The optimal outputs of pyrophyllite mechano-chemical activation in an ultra-centrifugal mill performing under different technological conditions were determined by analytical modeling and verified via Artificial Neural ...
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 ...

(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 ...
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 ...
What is the most relevant method for water absorption determination in ceramic tiles produced by illitic-kaolinitic clays? The mystery behind the gresification diagram
(Sociedad Espanola de Ceramica y Vidrio, 2020)
This study presents the 51 mixtures of ceramic clays characterized by using XRF, XRD, granulometry, and dilatometry analyses. After firing in a 1000-1250 °C range, water absorption (WA) according to EN standards by boiling ...
