Sažetak
In recent decades, the demands on concrete have increased beyond mere fulfilment of compressive strength requirements. Today, there is a demand for concrete with high resistance to aggressive environments so as to ensure the planned service life of structures. To provide for this high resistance, high-performance concretes are usually based on packing density achieved with a high proportion of fines provided by various supplementary cementitious materials. Silica fume and fly ash are some of the commonly used materials, while calcined clay and limestone are the emerging ones. The study presented in this paper aims to investigate the potential of different materials collected locally in Croatia for use as alternative supplementary cementitious materials in high-performance concrete. Initial experiments focused on the chloride migration resistance of four different combinations of mixed binders and a reference mix. Based on the results presented, the next phase will be to optimize high- performance concrete with calcined clays and fly ash.
