Abstract In this study, the usage of ground elastic wastes such as rubber in SCC is investigated. Rubber has replaced aggregates at the contents of 60, 120 and 180 kg/m3 in SCC by weight. Four different mixture proportions have been prepared. Moreover, 24 series have been produced by using six different viscosity agents in both SCC and rubberized self-compacted concrete (RSCC). By using these agents, it is attempted to see the effects of them on the properties of RSCC. Fly ash (FA) is used as filler material. The slump–flow, V-funnel, compressive strength, high temperature and freezing–thawing resistances of RSCC have been compared to the properties of ordinary SCC. At the end, it is observed that increase in RA content leads to increase in fresh properties of RSCC such as workability because of the existence of viscosity agents in mixtures. It decreases the hardened properties such as compressive strength and durability. However, the different viscosity agents can provide appropriate results for RSCC containing the same rubber aggregate (RA) content and the hardened properties of RSCC are better than the properties of ordinary concrete even if they are lower than the ones of SCC.

Properties and durability of concrete containing polymeric wastes (tyre rubber and polyethylene terephthalate bottles): An overview (2012, background): “Topçu and Bilir [24] studied the influence of rubber waste with a maximum dimension of 4 mm in self-compacting concretes noticing that rubber replacing sand increase concrete workability which is due to the presence of viscosity agents even to a volume of 180 kg/m3.”
A review of the fresh/hardened properties and applications for plain- (PRC) and self-compacting rubberised concrete (SCRC) (2010, background): “Topçu and Bilir [14] state that the chemical admixture type is the main factor controlling the workability of SCRC and that the fluidity increases in parallel with rubber content but with an increased risk of segregation.”
Impact Resistance of Rubberized Self-Compacting Concrete (2015, background): “…fresh and mechanical properties of RSCC have been studied in several studies (Bignozzi and Sandrolini, 2006; Güneyisi, 2010; Najim and Hall, 2010; Topçu and Bilir, 2009; Turatsinize and Garros, 2008), there is still a dearth of data on its impact resistance, transport and durability properties.”
