“…These observations were in agreement with those made by [10,18], who have carried out tests on an ordinary concrete containing treated rubber with NaOH. They concluded that the adhesion between rubber and cement paste has been improved by the chemical treatment of the rubber.…”

This study aims to analyze the possibility of valorizing rubber waste in roller-compacted concrete pavement (RCCP) mixes as aggregates. The rubber particles were added to the mix as partial replacement of the total volume of gravels at different rates (5, 10, 15, 20, 25, 30%). The experimental approach followed in this research consisted of studying the effects of the incorporated rubber on the mechanical properties of RCCP. The obtained results show that the incorporation of rubber changes the behavior of RCCP mixes. In presence of rubber, the RCCP became more ductile. The principal disadvantage of rubber incorporation was the decrease in the mechanical properties of RCC. To remedy this problem, the rubber particles were subjected to a treatment and silica fume was added to the mix. The obtained results showed that the performance of RCCP can be improved by modifying the surface roughness of rubber particles. Therefore, a large part of strength losses were corrected.

“…Raghavan et al [17] and Segre and Joekes [18], have studied rubberized concrete, and they reported that the strength losses might be justified by the low adhesion between rubber particles and the cement paste. Figure 5, shows how the poor adhesion of rubber with cement paste create a low strength areas.…”

“…According to literature data (Segre, Joekes 2000;Marques et al 2004;Segre et al 2002), different rubber pre-treatments are available, but the one most often applied is immersion in the saturated sodium hydroxide solution. Meanwhile, due to a high amount of alkaline in concrete during the exposure period, the presence of sodium hydroxide could be the determinant factor for the composite's durability (Marques et al 2008).…”

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 utilization of crumb rubber is not only beneficial in improving the properties of the asphalt binder but also highly favorable from a sustainability perspective and helps in reducing the carbon footprint. In addition to the use of crumb rubber in asphalt binders, researchers have explored the potential reuse of crumb rubber in cement-based materials (Segre and Joekes, 2000;Sukontasukkul and Wiwatpattanapong, 2009). Extensive studies have been conducted on the use of waste tire modified Portland cement concrete in highway construction.…”

Motivated by the tremendous trend toward green environment and to reduce the effect of scrap tires on the environment and human health, this research is an attempt to find a practical and environmentally sound solution of the problem of scrap tires by developing a light weight with low thermal conductivity composite construction materials using waste tires. A few literatures may be found about the effect of crumb rubber on thermal conductivity of mortar. Thus, in this research project, an experimental program was established to investigate the effect of the amount and size of crumb rubber (rubber obtained from recycling scrap tires) on the thermal properties of mortar. Four levels of crumb rubber addition: 10, 20, 30 and 40% and three sizes of crumb rubber (#30, #10_20 and a combination of both sizes) were considered to make twelve different mixtures of the rubberized mortar. Specially designed and constructed heat transfer measurement device was used to measure thermal conductivity of the specimens. Results were used to determine the optimal amount of crumb rubber that gives the least thermal conductivity, which directly related to the improvement in thermal resistance of concrete mixtures. It was found that the size and the amount of crumb rubber had an effect on thermal properties of the specimens investigated. The thermal conductivity of rubberized mortar was decreased by 28% when crumb rubber #10_20 was used. It was also found that #10_20 crumb rubber had more effect on the thermal conductivity reduction than #30 crumb rubbers. An empirical equation is proposed to predict thermal conductivity of rubberized mortar.
