“…It is noted that the addition of rubber granulates has decreased workability of the mixtures studied. Several researchers have shown that the shape and texture of rubber aggregates significantly affects the workability of concretes [13,31,32]. Thus, the deviation of the spherical shape leads to increase viscosity.…”

“…Small amount of entrapped air obtained in composites with rubber particles is due to better filling of empty pores at the rubber/cement interface, because of the presence of silica fume in the composite. Guneyisi et al (2004) indicate that 5% of rubber particles in the total volume of aggregate can be considered negligible in terms of concrete workability. On the contrary, the presence of steel fibres is associated with the decrease in concrete workability due to fibre tendency to interlock during the mixing process, which is also known as the "balling" effect .…”

Abstract. In line with current "green" transport initiatives, Croatia plans to build over the next investment period a high speed railway line which will connect central Croatia and its capital with coastal regions of the country. According to design documents, the track system will be built using ballastless concrete solutions. In the scope of the project "Concrete track system -ECOTRACK", researchers from the University of Zagreb -Faculty of Civil Engineering analysed a new material, i.e. the rubberized hybrid fibre reinforced concrete (RHFRC), in order to find out whether its properties are adequate for the proposed concrete track system. The RHFRC contains by-products from mechanical recycling of waste tyres (rubber and steel fibres). The study of fibre and rubber interaction and their contribution to mechanical properties of the fibre reinforced concrete is presented, as extensive research on positive interaction between industrial and recycled steel fibres has not as yet been made. The results show that the RHFRC is an innovative, sustainable and cost-effective concrete, which is fully compliant with criteria prescribed in relevant standards.Keywords: fibre reinforced concrete, industrial steel fibres, recycled steel fibres, mechanical properties, recycled rubber, waste tyre.

“…The major cause for the drop in the strength is the softness of the rubber particles are much softer due to this while compressive load applied to the specimen the crack propagation was very fast around the rubber particles which will affect the rubber-cement matrix and leads to the failure [12][13]. Two point load was applied to the specimens and the breaking load for the specimens were measured.…”

Abstract. In this paper, the experimental investigations was carried out to find the compressive strength, static modulus of elasticity and flexural strength of concrete mixtures, in which natural sand was partially replaced with Waste Tyre Crumb Rubber (WTCR). River sand was replaced with five different percentages (5%, 10%, 15%, 20% and 25%) of WTCR by volume. The main objective of the experimental investigation is to find the relationship between static modulus of elasticity and flexural strength with compressive strength of concrete with WTCR. The experimentally obtainedstatic modulus of elasticity and flexural strength results comparing with the theoretical values (various country codes recommendations).
