Гранична носивост армиранобетонских гредних носача од бетона са великим садржајем летећег пепела
(Универзитет у Београду, Грађевински факултет, 2018)
Бетон је један од најчешће коришћених материјала данашњице. Међутим,током производње цемента, испушта се приближно једна тона CO2 за свакутону произведеног портланд цементног клинкера. До сада је уложено пунотруда у ...
Behaviour of Reinforced Concrete Beams Made with Recycled and Waste Materials Under Long-Term Loading
(Универзитет у Београду, Грађевински факултет, 2018)
Concrete is the second most-used material in the world after water and its productionplaces a large strain on natural resources and the environment. This has prompted thesearch for sustainable alternatives to traditional ...
Experimental investigation of basic concrete properties for 3D printing technology
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije (DIMK)Udruženje savremene industrije glinenih proizvoda Srbije, 2022)
The aim of this paper is an experimental investigation of fresh concrete properties of the mixture designed for 3D printing. Different mixtures with and without chemical additions (superplasticizer and hydration controller) ...
Fiber reinforcement mortars and concretes: The possibilities of improvement physical - mechanical properties / Mikroarmirani malteri i betoni - mogućnost poboljšanja fizičko-mehaničkih svojstava
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2006)
Basic properties of fiber reinforcement mortar and concrete type composites have been represented in the paper. The results of authors' own laboratory testing of two concrete types as well as two mortar types are shown. ...
Истраживање параметара дуктилности и ударне отпорности ситнозрних бетона микроармираних синтетичким влакнима / Research of ductility and impact resistance related parameters in synthetic fiber reinforced concrete
(2010)
Микроармирани бетони (МАБ) представљају композитне материјале добијене
армирањем цементне матрице равномерно диспергованим влакнима. С обзиром на
чињеницу да класичан бетон слабо подноси напоне затезања, поседује низак ...
Timber-concrete composite structures / Spregnuti nosači drvo-beton
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2000)
Classical composite steel-concrete beams are being used in construction practice already for a long time. However, in the recent few years a new form of composite beams in which wood is used instead of steel, is more and ...
Effect of aggregate type and fly ash content on properties of self-compacting concrete
(Akademija nauka i umetnosti Republike Srpske, 2019)
The paper presents the results of experimental study of Self-Compacting Concrete in fresh and hardened state. Five mixtures were made, in which the content of the following components was varied: aggregates, fly ash in ...
Examples of performance improvement of concrete and mortar by means of fiber reinforcement / Primeri poboljšanja performansi betona i maltera putem mikroarmiranja
(Univerzitet u Novom Sadu - Građevinski fakultet, Subotica, 2005)
The basic properties of fiber reinforced composites (concrete and mortar) are presented in this paper. Based on their own experimental testing results, the authors analyze the examples of performance improvement of fiber ...
Redistribution of internal forces in composite concrete girders made continuous vs. time / Preraspodela uticaja kod naknadno kontinuiranih spregnutih armiranobetonskih nosača tokom vremena
(Univerzitet u Nišu, Niš, 2011)
Research on the long-term behavior of composite concrete girders made continuous is presented in the paper. Concrete precast element is cracked under construction load. Creep and differential shrinkage of precast and in-situ ...
Physical and Mechanical Properties of Concrete Cured at Low Temperatures
(Business Technical College, Uzice, 2017)
The paper reports the results of experimental tests of physical and mechanical properties of concrete which hardened in cold weather conditions without curing, without protection against precipitation and also without ...
