Using recycled materials in concrete is a way to make the process of making concrete more economical and environmental. The use of non-renewable resources for construction is a major concern that has irreparable result for the environment. In this study, mechanical properties of self-compacting mortars containing waste materials such as recycled bricks (RB), concrete (RC), ceramics (RR) and tiles (RT) were investigated. The substitution percentage of waste material was 5, 10 and 15% replacing cement. Incorporating super plasticizer (SP) on different properties of samples was evaluated. The results of fresh mortars and also compressive strength and water absorption were assessed. The compressive strength of samples decreased slightly by using waste materials. However the percentage of decrease was between 3 and 17% that does not cause major disasters to the samples. Also water absorption results indicated an increase as waste materials were incorporated. The obtained results demonstrated that the properties of samples have only a slight difference, and that the recycled materials can successfully be utilised for making of self-compacting concrete. This innovative procedure and findings and recommendations of this research can contribute to boosting the use of recycled aggregates in the construction sector and make it a sustainable activity.
