“…Possible synergy of industrial and recycled steel fibres could result in significant economic savings, and also in considerable environmental benefits, without influencing concrete properties, which is why this material can rightly be characterized as extremely viable. Benazzouk et al (2006) and Khaloo et al (2008) indicate that rubber particles have the capability to entrap air, due to their rough surface and non-polar nature. The presence of 5% of rubber particles in the total volume of the aggregate did not cause considerable changes in concrete microstructure (Table 3).…”

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 concrete incorporating tire rubber waste is expected to have higher fracture and cracking resistance. Siddique and Naik [7], Khaloo et al [8] showed in an experimental investigation that the addition of rubber decreases the material unit weight. For structural applications of lightweight concrete, strength decreased and reduces the dead load, foundation size and construction coasts.…”

“…khaloo et al [5], ont examiné l'utilisation des granulats en caoutchouc pour fabriquer le béton et une chute de la masse volumique du béton avec l'augmentation du taux de substitution de caoutchouc a été observée. Cependant, Siddique et Naik [6] ont rapporté aussi une augmentation de la teneur en air occlus dans la matrice cimentaire contenant des particules de caoutchouc qui a une réduction de la masse volumique.…”

Used tyre rubber wastes present a serious environmental problem of pollution and storage. The recycling of this waste in the industry of construction could be an appropriate solution to produce an eco-concrete and could contribute to the improvement of some of its properties. This paper aims to study the possibility of using tyre rubber waste as fine aggregate replacement in self-compacting concrete (SCC). Fines rubber particles of 0-2 mm of waste tyres were added SCC mixtures as a partial substitution of the total volume of sand at different percentages (5, 10, 15, 20 and 30%). The influence of fines rubber of used tyres on fresh and hardened properties of the SCC was investigated. The fresh properties of SCC were performed by using slump-flow, T50 flow time, L-box, V-funnel and segregation resistance tests.Characteristics of the hardened state were obtained by compressive strength and thermal conductivity. The experimental results showed that the inclusion of fines rubber in SCC decreases the workability, reduced its passing capacity and increases the possibility of blocking. A decrease in compressive strength is observed with the increase in rubber content.On the other hand, the incorporation of the rubber fines aggregates enhances in a remarkably way the thermal conductivity.Résumé : Les pneus usagés présentent des problèmes de pollution de l'environnement et de stockage. Le recyclage de ces déchets dans l'industrie de construction, s'avère une solution adéquate pour la production d'un éco-béton et peut contribuer à l'amélioration de certaines de ses propriétés. Cet article vise à étudier la possibilité de la valorisation des déchets caoutchouteux des pneus usagés sous forme de granulats dans le béton autoplaçant (BAP). Des particules de caoutchouc de 0-2mm de pneus ont été ajoutées aux mélanges du BAP en substitution partiel du volume total de sable à différents pourcentages (5, 10, 15, 20 et 30%). L'influence du caoutchouc sur les propriétés du BAP, aussi bien à l'état frais qu'à l'état durci, a été analysée. Les propriétés à l'état frais ont été déterminées à l'aide de tests du diamètre d'étalement et du temps d'écoulement, de L-box, du temps d'écoulement à l'entonnoir en V et de la résistance à la ségrégation par tamisage. Les caractéristiques à l'état durci ont été obtenues par l'essai de la résistance à la compression et la conductivité thermique. Les résultats expérimentaux ont montré que la présence du caoutchouc dans le BAP diminue l'ouvrabilité, réduit sa capacité de passage et augmente la possibilité de blocage. Une chute de la résistance à la compression est observée avec l'augmentation de taux de caoutchouc. Par contre, l'incorporation des granulats de caoutchouc améliore d'une façon remarquable la conductivité thermique.
