Structural design of polymer protective coatings for reinforced concrete structures. Part I: Theoretical considerations

open access: yesJournal of Civil Engineering and Management, 2007
In a number of situations reinforced concrete structures must be protected by barrier materials to prevent contact with aggressive agents. One of the ways to protect concrete structures from corrosion is to use protective polymer coatings.

Modelling the carbonated concrete realkalization

open access: yesJournal of Civil Engineering and Management, 2009
The presented model of carbonated concrete realkalization is compiled on the basis of the multi‐component medium theory equations. The process equations have been obtained from an analysis of the partial equations of mass, electric charge, momentum ...

Površinska korozija na oplati zrakoplova

open access: yes, 2019
Korozija predstavlja proces koji ima posebno važan utjecaj u zrakoplovstvu. Korozijsko djelovanje može oštetiti zrakoplov, prouzrokovati mehaničke i elektroničke probleme, a samim time ugroziti ljudske živote i povećati financijski trošak održavanja ...

Stress‐strain concentrations in high‐rise structure elements and monotonic disintegration under the influence of environment contamination

open access: yesJournal of Civil Engineering and Management, 2005
Abundance of metal masts and towers, their aging require to pay attention to corrosion phenomena and their after‐affects. Special attention should be paid to the changes of structural elements strength and strain (induced by the environment ...

Accelerated carbonation depth test in an atmosphere of 98% CO2

open access: yesEngineering Structures and Technologies, 2011
The action of atmospheric carbon dioxide is one of the agents which substantially reduce the durability of concrete structures. Th is so called carbonation is one of the corrosive processes influencing properties of mature concrete.

The Role of Epikarst in the Morphogenesis of the Karstic Forms, Especially Hollow Forms in Greece

open access: yesActa Carsologica, 2016
Vloga epikrasa pri nastanku podtalnih škrapelj in kraških depresij, je različna. Prevotljene škraplje in podtalne škraplje tipa »kluftkarren« so prekrite s kraško prstjo in kažejo na delovanje vode.

Mineral waters of Serbia and development of phototrophic microbial communities near points of emergence and on wellheads

open access: yesActa Carsologica, 2017
Phototropic microorganisms in thermal mats had not attracted enough attention in Serbia in the past. The research presented in this paper is the first to address biofilms at selected occurrences of mineral water in Serbia (Bogatić, Metković and Belotić ...
