Modul elastičnosti betona sa agregatom od reciklirane opeke / Modulus of elasticity of concrete with aggregate of recycled brick
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2002)
Na osnovu zavisnosti napona i deformacija pri kratkotrajnom opterećenju može se definisati područje elastičnih i plastičnih deformacija, karakter loma, maksimalna deformacija pri lomu. U ovom članku su prikazani radni ...
Toplotna provodljivost betona sa agregatom od reciklirane opeke / Thermal conductivity of concrete with aggregate of recycled brick
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2001)
Termička svojstva materijala u primeni određuju takozvane projektne termičke vrednosti koeficijenata toplotne provodljivosti građevinskih materijala. Predmet rada su rezultati serije laboratorijskih merenja koeficijenata ...
Polymer modified concrete with expanded polystyrene grains reinforced with polypropylene fibers
(American Concrete Institute, 2001)
Lightweight concrete with lower water absorption for thin structural elements was goal of investigation. Polypropylene fibers contributed to concrete ductility. For lower bulk density we used polystyrene grains. We used ...
Static and impact crack properties of a high-strength steel welded joint
(Elsevier Sci Ltd, Oxford, 2007)
in order to gain the benefits of weldable high-strength steels in pressurized equipment applications, satisfactory toughness and crack properties of the welded joint, both in the weld metal and the heat-affected-zone (HAZ), ...
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 ...
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 ...
Influence of different bonding and fluxing agents on the sintering behavior and dielectric properties of steatite ceramic materials
(Elsevier Sci Ltd, Oxford, 2017)
The focus of the study was on providing insights into interconnections between sintering and development of the crystalline microstructure, and consequently variations in dielectric behavior of four steatites fabricated ...
Study on the addition effect of metakaolin and mechanically activated kaolin on cement strength and microstructure under different curing conditions
(Elsevier Sci Ltd, Oxford, 2017)
The effects of thermally (MK) or mechanically activated kaolin (AK) on the compressive strength of mortars and microstructure of pastes were investigated. Mortar mixtures, in which 10%, 20% and 30% of ordinary Portland ...
Mechanically activated coal ash as refractory bauxite shotcrete microfiller: Thermal interactions mechanism investigation
(Elsevier Sci Ltd, Oxford, 2014)
A growing demand for refractory castables with advanced properties has given rise to a continuous technological evolution and highlighted the necessity for secondary raw materials reapplication even in refractory industry. ...
