Sažetak
This paper aims to investigate the possibility of utilizing steel slags locally produced in Croatian plants as a concrete aggregate. Therefore, eight concrete mixtures were prepared with coarse slag fractions and different binders whose hardened state properties (compressive strength, static modulus of elasticity, volume changes and corrosion susceptibility) were then compared with the properties of reference concrete made of commonly used natural aggregate materials, dolomite. According to the obtained test results it can be concluded that concrete containing slag possess acceptable mechanical properties and volume changes for its structural use but could represent a risk in terms of corrosion of reinforcement in case of slag with higher amount of sulphur in its chemical composition.
