Abstract

Jedan on najbitnijih parametara za životni vijek i kvalitetu konstrukcije je trajnost betona. Na trajnost betonske konstrukcije utječu razna djelovanja iz okoliša, sastav, svojstva, kvaliteta i održavanje betona. Također, trajnost konstrukcije ovisi o mogućnosti penetracije agresivnih tvari u beton odnosno o propusnosti, difuziji i kapilarnom upijanju. U radu je prikazano eksperimentalno ispitivanje kapilarnog upijanja te fizikalnih svojstava betona gustoće i poroznosti. Uzorci na kojima je provedeno ispitivanje su dobiveni bušenjem iz konstrukcija na različitim lokacijama. Konstrukcije iz kojih su izvađeni uzorci su: Luka Gaženica u Zadru, Luka nautičkog turizma Mandalina - Kuline u Šibeniku i Pomorski putnički terminal na riječkom lukobranu.

Abstract (english)

The durability of concrete is one of the most important parameters for the service life and quality of structures. The durability of a concrete structure is affected by various effects from the enviroment, quality, composition of the concrete and the maintenance of the structures. The durability of the structure also depends on the possibility of penetration of aggressive substances into the concrete, in other words, it depends on permeability, diffusion and capillary absorption. The final paper presents an experimental testing of capillary absorption and the physical properties of concrete- density and porosity. The samples on which the experimental test was carried out were obtained by drilling from structures at different locations. The constructions from which the samples were taken are: the port of Gaženica in Zadar, the port of nautical tourism Mandalina-Kulina in Šibenik and the passenger port terminal at the breakwater Rijeka.
