Abstract: The increasing downside of tire waste disposal in Iraq is often alleviated, if new ways of working for excess tires are found. One of the most important ways in construction. However, the use of waste tires in engineering is very low at present. The increasingly negative trend of tire waste disposal in the Republic of Iraq is often reduced if modern working methods are created for excess tires. The use of recycled tire rubber as a partial replacement from Coarse Aggregate (CA) can be very positive to have an influence on the mechanical properties of concrete. The most popular building materials is concrete technology. For that reason, construction modification often seeks to exaggerate its uses and applications, increase its properties and reduce cost. The purpose of the pilot school education is to ascertain the recycled concrete properties of the vehicle tires in the past and to act as a partial replacement of the aggregates. The tests were conducted on concrete samples containing 0, 10, 15 and 20% of the rubber as a total. The replacement of aggregate by rubber in concrete has resulted in reduced compressive strength and density. Decrease in strength depend on the amount of rubber. The loss of mechanical strength and relatively high change in durability prevent the widespread use of scrap tires in concrete. Additional construction materials were examined during this study to reduce the loss of mechanical specifications in rubber-coated concrete. Therefore, some mixtures on fly ash include cement swap of 15% by volume. The results reveal that apart from a slight improvement in the strength of coated rubber, the synergistic result of the pre-coated vats and fly ash as an alternative to cement significantly increased the mechanical properties of the mixtures.
