Sažetak
Currently, Croatia is undertaking significant efforts to ensure funds for construction of railway con-nection between its continental and coastal regions. Construction of high speed railway is planned using concrete blastless track system. Technology and material needed to satisfy requirements for named track system are currently not available in Croatia. Overall goal of the presented research is to prepare concrete which could satisfy prescribed requirements on one side and on the other, provide ecological and economical savings. Presented rubberized hybrid fibre reinforced concrete (RHFRC) is tailored based on previous experi-ence and available quantities of by-products from mechanical recycling of waste tyres. For purpose of material optimisation, 20 concrete mixtures are prepared with different recycled/industrial (steel and textile) fibre ratio and with addition of fine rubber particles (0.5–2 mm). More than 1 000 concrete specimens are prepared and tested on 16 different standardized tests. In this paper, investigation of compressive strength, modulus of elasticity, toughness, capillary absorption, resistance to wear and freeze-thaw cycles will be represented on selected concrete mixtures. Obtained results indicate that by partially replacing industrial with recycled fibres together with addition of fine rubber particles (5% on total volume of aggregate) good quality RHFRC can be prepared, assuring significant economic savings due to steel deficiency and its rising prices.
