Abstract

Korozija je proces raspadanja konstrukcijskog materijala djelovanjem različitih agensa te kao takva može dugotrajno naštetiti integritetu, a time i funkcionalnosti čeličnih mostova. Ako se ne primijeni adekvatna zaštita ili se ostavi potpuno nezaštićen, konstrukcijski čelik će pod utjecajem okoliša vrlo brzo korodirati što može dovesti do negativnih posljedica u pogledu troškova ili u gorem slučaju, do sigurnosnog rizika. Najčešći oblici korozije koji se manifestiraju na čeličnim mostovima su jednolika korozija, galvanska korozija, korozija u procijepu, jamičasta korozija, interkristalna korozija, erozijska korozija i napetosna korozija koje će detaljnije biti opisane u ovom preglednom radu. Iako ne postoji univerzalno rješenje ovog problema, razmotrit ćemo neke najprimjenjivanije tehnike u očuvanju čeličnih mostova kao i metode korištene pri njihovim periodičnim inspekcijama koje se provode s ciljem pravovremene detekcije i sanacije oštećenja.

Abstract (english)

Corrosion is a process of disintegration of structural material by the action of various agents, and as such it can permanently damage the integrity and thus the functionality of a steel bridge. If adequate protection is not applied or left completely unprotected, structural steel will corrode very quickly under the influence of the environment, which can lead to negative consequences in terms of costs or, in the worst case, to safety risks. The most common forms of corrosion manifested on steel bridges are uniform corrosion, galvanic corrosion, crevice corrosion, pitting corrosion, intergranular corrosion, erosion corrosion and stress corrosion, which will be described in detail in this paper. Although there is no universal solution to this problem, we will consider some of the most applicable techniques in the preservation of steel bridges, as well as the methods used during their periodic inspections, which are carried out with the aim of timely detection and repair of damage.
