Scrap tires are counted as one of the non-recyclable materials in nature, which cause environmental male effects. In the present research, the feasibility of applying scrap tire rubber in concrete is investigated. In this regard, some laboratory specimens are made and tested in two major groups. In the first group: crumb rubber was used instead of coarse aggregate and, in the second group, rubber powder was used instead of cement. A compressive strength test was done to recognize the strength behavior of the specimens and to investigate their durability under different conditions, two of the most significant tests (including: permeability and water absorption) were done.The results revealed that the trend of strengthening in a 28-day-period could be determined via an experimental equation, which is conservative, and their compressive strength is similar to ordinary concrete. It is also to be mentioned that no signiffcant changes in durability will occur, if the substitution percentage does not exceed a special limit.
