Therefore, paying attention to the waste materials and recycling them help to protect the environment. During the last decades, reusing these materials was the main concern and accepted by the researchers, governments, and people around the world. In this paper, using of the industrial waste materials such as glass, rubber, and plastic (ABS) as aggregate in concrete are investigated. Many samples are made and tested to study the effect of these materials on the concrete characteristics. Compressive strength, slump, water absorption and density were the main characteristics of the evaluation. Since there are many criteria available to decide which of the waste materials are the best, using Analytical Hierarchy Process (AHP) the selected waste materials are sorted and the best one is given. The influence of the combination of these materials on the concrete are also investigated.
