The use of solid wastes is not a new concept in concrete industries, but still in its early stages in the growing countries. There is a need to realize the value of recycling the crumbed rubber tires accumulated every year in Saudi Arabia and its use in concrete mixes. The objectives of the paper are to investigate the feasibility of incorporating tire crumb rubber as a replacement for natural mineral aggregates in concrete, study the influence of curing time on the compressive strength, and the engineering properties of concrete mix design with and without crumbed rubber. An important consideration has been acknowledged the development of rubberized concrete products which are feasible in terms of production and have some market potential. Three different concrete groups were prepared and tested in terms of compression. The mechanical test results demonstrated that the use of crumb rubber reduced all types of compressive strength. The different crumb rubber sizes have some influence on the mix and can be considered as structural light and moderate weight concrete.
