Sulphur concrete
(Structural Engineering Conferences, SECON, 2007)
Sulphur concrete is a relatively new material, and although similar in final appearance to portland cement concrete, its manufacture, handling, use, and testing are different. Sulphur concrete is a thermoplastic material ...
Comprehensive approach to the influence of frequently used secondary raw materials on clay bricks quality using mathematical modeling (a systematic review)
(Elsevier Sci Ltd, Oxford, 2018)
The main idea of this research was to evaluate rice and sunflower hulls, sawdust and their ashes, as additives in clay brick production using mathematical analysis. All available papers, containing the parameters of interest, ...
Failure analysis of the end eye connection of the bucket wheel excavator portal tie-rod support
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper describes the failure analysis results of the bucket wheel excavator (BWE) portal tie-rod support. The results of finite elements analysis (FEA) point out the occurrence of pronounced stress concentration, whereby ...

(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2009)
Novousvojeni srpski standardi SRPS EN 1367-5:2007 Određivanje otpornosti agregata prema toplotnom šoku i SRPS EN 1367-3:2008 Ispitivanje agregata bazalta iskuvavanjem na znake zonenbrand procesa su dve potpuno nove metode ...
Direktive EU i standard EN 12341 - osnov za specifikaciju nove metode u imisionom određivanju čestica veličine 1oμm
(Poslovna politika AD, Beograd, 2005)
Postojeća regulativa Republike Srbije iz oblasti zaštite životne sredine predviđa, između ostalog, zaštitu vazduha kao preduzimanje mera sistematskog praćenja kvaliteta vazduha, i pri tom definiše suspendovane materije kao ...
Structural Integrity Assessment of Welded Pressure Vessel Produced of HSLA Steel
(Journal Iron Steel Research Editorial Board, Beijing, 2011)
Welded joint is a critical region of a welded structure. The operational safety of welded pressure equipment mostly depends on the behaviour of loaded weldments. Safety of welded structure is dependent on the properties ...
Characterization of raw clay materials in Serbia 0.063mm sieved residues
(American Ceramic Society, 2009)
Particle size is the effective diameter of a particle as measured by sedimentation, sieving, or micrometric methods. Particle sizes are expressed as classes with specific, effective diameter class limits. The broad classes ...
Recycling of waste coal dust for the energy-efficient fabrication of bricks: A laboratory to industrial-scale study
(Elsevier, Amsterdam, 2021)
In this study, an optimal mixture of loess brick clays and waste coal dust in laboratory hollow blocks production is determined with the aim of promoting sustainable development in terms of saving resources and energy. The ...
ANN model of brick properties using LPNORM calculation of minerals content
(Elsevier Sci Ltd, Oxford, 2014)
Mineralogical composition of heavy clays is one of the most important properties when stadying raw materials in brick industry. Within this study, quantitative determination of minerals using LPNORM calculation was performed, ...
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 ...
