چکیده

The development of environmentally accepted methods of used tire disposal is one of the greatest challenges that waste management experts face today. Use of waste rubber particles as aggregate in self-compacting concrete is a suitable solution for the environmental hazards of waste tires being produced on a large scale. The aim of this work is to investigate the influence of the size of waste rubber particles and the waste replacement volume on the fresh and hardened properties of self-compacting waste rubberized concrete (SCWRC). Tire rubber particles were used in two groups to replace 5%, 10%, 15% and 20% of fine (GRSCC) and coarse (CRSCC) aggregate, separately. The water to cement ratio used in the concrete mixes was 0.42. The experimental results showed that the workability, water absorption and mechanical properties such as compressive and flexural strengths and ultrasonic pulse velocity of SCWRC reduced with the increase of rubbercontent.
