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/m(3) 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.
