Uticaj zamene cementa krečnjačkim filerom na svojstva betona
(Univerzitet u Beogradu Građevinski fakultetDruštvo građevinskih konstruktera Srbije, 2021)
U radu su prikazana eksperimentalna ispitivanja jedne vrste zelenih betona kod kojih je Portland cement zamenjen sa dve vrste krečnjačkog filera istog porekla i mineraloškog sastava, a različite finoće mliva. Projektovano ...
Compressive strength of green concretes with low cement and high filler content
(Society for Materials and Structures Testing of SerbiaUniversity of Belgrade Faculty of Civil EngineeringAssociation of Structural Engineers of Serbia, 2021)
It is estimated that by the end of the current decade, about 26% of clinker will be replaced by suitable alternative materials, among which limestone filler probably has the greatest potential due to its wide availability ...
Application of Copper Mining Waste in Radionuclide and Heavy Metal Immobilization
(Wiley-VCH GmbH, Weinheim, 2021)
Copper slag flotation tailings (CSFT), as the end waste from copper mining, are evaluated for radionuclide and heavy metal immobilization. Characterization of CSFT based on grain size and mineral composition, surface ...
Influence of Silica Fume on SCC Concrete Properties
(University of Belgrade ‐ Technical Faculty in Bor, 2021)
The use of recycled materials or waste increases sustainability in the construction sector. Likewise, the self-compacting concrete (SCC) has shown improvement in mechanical properties, when made with some waste pozzolanic ...
Primena grejnih kablova u izvođenju betonskih radova pri ekstremno niskim temperaturama sa numeričkim primerima
(Udruženje inženjera građevinarstva geotehnike arhitekture i urbanista, 2021)
Očvršćavanje betona u uslovima niskih temperatura dovodi do usporavanja procesa
hidratacije cementa. U ekstremnim uslovima može doći do prekidanja hidratacije cementa i
pojave smrzavanja vode u betonu. Sve to može dovesti ...
Extension of the ζ-method for calculating deflections of two-way slabs based on linear elastic finite element analysis
(wileyonlinelibrary.comfib. International Federation for Structural Concrete, 2021)
Deflections are among the most complex aspects of reinforced concrete behavior.
Furthermore, deflection control is increasingly a governing criterion in
design, especially in the case of two-way members such as flat slabs ...
The new buckling curves for cold-formed stainless steel equal-leg angle columns
(Building Materials and Structures, 2021)
The design rules for centrically compressed stainless steel equal-leg angle
members are not explicitly stated in the current European standard SRPS EN 1993-
1-4. This paper summarizes the results of extensive ...
Development and assessment of a modified ζ-method for deflection control of two-way slabs
(fib Symposium. "Concrete Structure: New Trends for Eco-Efficiency and Performance: 18th fib Symposium proceedings", 14-06-2021)
Deflection control of two-way slabs is a very complex task considering their possible geometries, structural systems, reinforcement layouts and loading histories, as well as the large number of influencing parameters and ...
