Description The construction of road infrastructure of the Corridor X through Serbia, according to design documents, required concretes of a variety of classes and special properties. Depending on the type of structures and their structural elements (piles, bridges, tunnels) the concrete class ranged from C 25/30 to C 45/55. The special properties required were: resistance to frost, resistance to simultaneous action of frost and defrosting salts and water tightness. Overall, those are concrete mixtures which can be designed relatively easily with quality materials. In practice, however, a problem occurred, as the contractor required using of the materials, i.e. aggregates, from the nearest locations. Experience acquired in those concrete mixes design once again confirmed how large impact aggregates have on concrete properties. As a result, many aggregates from the local screening plants were not adequate choice in mixing of the concretes having the required properties. The paper presents the mix designs for concrete, designed with various aggregates, as well as the properties of concrete in fresh and hardened states.
