Abstract: The paper presents possibility of usage of recycled materials, tire powder and wood biomass ash, as fillers for self-compacting concrete (SCC). Fly ash and dolomite powder are found to be the traditional materials used in controlling the segregation potential and deformability of fresh SCC. This research deals with the utilisation of an alternative materials, tire powder and wood biomass ash, instead of 5%, 10%, 15% and 20% of dolomite powder, to produce SCC. For this study, nine mixtures were prepared. Fresh SCC properties were assessed by means of slump flow, L-box and J-ring, while hardened properties were evaluated by means of compressive strength and modulus of elasticity at age of 28 days. The results are positive: recycled fillers can partially replace dolomite filler and at the same time satisfactory maintain fresh and hardened concrete properties.
