Abstract

Završni rad obrađuje tematiku betoniranja pod vodom. Prilikom gradnje mostova, brana i njima sličnih konstrukcija nameću se novi zahtjevni za beton pod vodom. Cilj ovog rada je upoznati se sa počecima podvodnog betoniranja i njegovim razvojem. Upoznaju se današnje tehnike i metode te analiziraju faktori koji utječu na trajnost konstrukcije prilikom izlaganja agresivnom morskom okolišu. U radu su obrađeni i zahtjevi betona u morskom okolišu koji prilikom projektiranja prate određene norme. Obrađuju se zahtjevi za cement, razred izloženosti, agregat, vodocementni omjer, zaštitni sloj betona kao jedan od najvažnijih zahtjeva, pukotine i sadržaj klorida u betonu. Opisani su i mineralni dodaci koji poboljšavaju svojstva betona za podvodnu ugradnju. Na kraju rada dan je primjer mosta koji je uzdignut iz mora i nalazi se na području Republike Hrvatske.

Abstract (english)

The final paper deals with the topic of concreting under water. During the construction of bridges, dams and similar structures, new demanding concrete under water are imposed. The aim of this paper is to get acquainted with the beginnings of underwater concreting and its development. We get to know today's techniques and methods and analyze the factors that affect the durability of the structure when exposed to the aggressive marine environment. The paper also deals with the requirements of concrete in the marine environment, which during the design follow certain norms. We process the requirements for cement, exposure class, aggregate, water cement ratio, concrete protective layer as one of the most important requirements, cracks and chloride content in concrete. At the end of the paper, we give an example of a bridge that was raised from the sea and is located on the territory of the Republic of Croatia.
