The presence of waste products from various human activities is one of the environmental problems and extensive research is being done to reduce these damages to the environment. Rubber tires are materials that cause environmental pollution due to non-decomposition. This research has provided the preconditions for reducing environmental pollution from used tires by replacing crumb rubber instead of aggregate used in concrete. Countless efforts have been made to improve the strength of concrete containing rubber wastes, but it is still necessary to comprehensively examine their effect on the mechanical properties of concrete. The study looked at the durability of concretes made with 5, 10, and 15 percent of rubber substitutes for sand and prepared 370 samples, which showed that the use of retail tires reduces the compressive strength of concrete. Increasing energy absorption, reducing permeability and ultimately improving the performance of concrete, which by choosing the optimal percentage of crumb rubber can be produced concrete with the desired compressive strength with better performance and longer service life.
