Sažetak
The aim of the study presented in this paper is to research the possibility of replacing polypropylene fibres (PP) in concrete with recycled polymer fibres obtained from end-of-life tyres (RTPF). Therefore, reinforced concretes with RTPF mixed with rubber particles, as received from the factory, (in amounts of 5, 10 and 15 kg/m3) and mechanically cleaned RTPF (in amounts of 1, 2 and 5 kg/m3) were tested in compare with plain ordinary concrete and concrete with 1kg/m3 of polypropylene (PP) fibres. Study comprised testing of fresh concrete properties (workability, air content and density), mechanical properties (compressive strength and modulus of elasticity) and early age deformations. Obtained results showed significant reduction in early age deformations within concrete mixes utilising RTPF compared to reference mixes with negligible difference in mechanical properties, in the same time.
