Assessment of intensive grinding effects on alumina as refractory compound: Acceleration of gamma to alpha phase transformation mechanism
(Elsevier Sci Ltd, Oxford, 2014)
In this study, the feasibility of alumina phase transition enhancement by mechanical activation was conducted. It was showed that the milling environment plays an important role on the physical, chemical and thermal behavior ...
Numerical determination and experimental validation of the fracture toughness of welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Most of the serious weldment failures lead to catastrophic consequences in terms of damage of other equipment, loss of production, and risks to workers' health and safety. Hence, there is motivation to find margin between ...
Neka svojstva betona na bazi reciklirane opeke / Some properties of concrete based on recycled brick
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2000)
U radu je prikazana mogućnost upotrebe reciklirane opeke kao agregata za beton. Eksperimentalni rod je uključio vise vrsta betona spravljenih sa dve količine cementa (250 i 350 kg/m) i sa ili bez dodatka polimera. Kao ...
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 ...
Investigation of the optimal parameters for repair welding of the coal mill in the fossil power station
(Welding in the World, 2008)
As a part of the coal fired power stations a coal milling plant is important, as it supplies a coal and air mixture for combustion in a power plant. Coal milling plant is involved in wearing process, since the raw coal is ...
Welded joints behaviour in service with special reference to pressure equipment
(Springer, Dordrecht, 2009)
Quality and structural integrity of welded pressure equipment are defined by The Pressure Equipment Directive (97/23/EC). The problem is complex, due to welded joint imperfections, matching effect, heterogeneity of ...
An analysis of the influence of weldment heterogeneity in ferrite-austenite welded structure
(Welding in the World, 2009)
An analysis of the influence of heterogeneity of the ferriteaustenite welded joint on its integrity has been performed. The Charpy specimens, with notch positioned in different regions of welded joint, have been tested ...
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 ...
