Abstract: 
The aim of this paper is to demonstrate that by using industrial and recycled steel fibres together with recycled rubber, high quality rubberized hybrid fibre reinforced concrete (RHFRC) can be prepared. In such way, environmental and economic savings are provided without significant influence on mechanical and durability properties of concrete.

Nine concrete mixtures were prepared and compressive strength, capillary absorption, water permeability, chloride diffusion, gas permeability and resistance to freezing and thawing were tested. Mixtures were prepared with different steel fibre ratios (only industrially fibres, combination of industrially and recycled fibres, only recycled fibres) and 5% fine rubber aggregate replacement. Special focus of this research is the possibility of utilization of recycled rubber as an admixture responsible for improvement of concrete resistance to freezing and thawing cycles.
