The influence of the raw material grinding fineness on the brick industry products quality
(Trans Tech Publications Ltd, Durnten-Zurich, 2002)
The brick industry development trends have two main directions: high product quality and use of lower quality clays and secondary (recycled) raw materials, The development trends reflect today's market requirements - ...
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 ...
Compressive strength and microstructure of ordinary cured and autoclaved cement-based composites with mechanically activated kaolins
(Elsevier Sci Ltd, Oxford, 2018)
The effects of two different mechanically activated kaolins, AKV (61% kaolinite, 14% quartz and 16% mica) and AKG (51.6% kaolinite and 40.6% quartz) on the compressive strength of cement composites and microstructure of ...
