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 ...
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 ...
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 ...
An analysis of impact testing of high strength low-alloy steels used in ship construction
(Univ Zagreb Fac Mechanical Engineering & Naval Architecture, Zagreb, 2021)
Brittle damages have been examined widely since welding became common practice when it comes to carrying out robust structures. Welded structure of the ship hull has to be continuous. Brittle damages that occur on hull ...
Aplitic Granite Waste as Raw Material for the Production of Outdoor Ceramic Floor Tiles
(MDPI, 2022)
One of the significant problems in the production of ceramic tiles is the very high consump-tion of natural resources such as clay, feldspar, and quartz. The possibility of replacing part of the formulation of ceramic ...
Numerical model of fluid-structure interaction for water tower analysis of vibrations
(Institut za ispitivanje materijala, BeogradDruštvo za integritet i vek konstrukcija (DIVK), 2020)
This paper deals with the aspects of vibration analysis of 3D numerical water tower models with the explicitly generated 3D finite element (FE) solid fluid model that simulates the fluid-structure interaction (FSI). The ...
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 ...
Fired pressed pellet as a sample preparation technique of choice for an energy dispersive X-ray fluorescence analysis of raw clays
(Elsevier, 2022)
In this paper, the main subject concerns comparing different techniques to prepare raw clay samples for energy dispersive X-ray fluorescence spectrometry (EDXRF). Three kinds of sample preparation procedures are examined,such ...
Life Assessment of Corroded Wire for Prestressing
(MDPI, 2023)
The repair of structural elements for the prestressing of reinforced concrete is necessary
when existing prestressing wires are damaged or after a certain period of time. The objective of this
paper is to describe the ...
Structure and properties of ZnO/ZnMn2O4 composite obtained by thermal decomposition of terephthalate precursor
(Journal of the Serbian Chemical Society - JSCS, 2022)
A biphasic [Mn(dipya)(H2O)4](tpht)/{[Zn(dipya)(tpht)]·H2O}n complex material, I, (dipya = 2,2’-dipyridylamine, tpht2– = dianion of terephthalatic acid) was synthesized by ligand exchange reaction and characterized by XRPD ...
