The increasing number of rubber wastes and their depots is a significant environmental problem. These wastes can be used to improve soils. On the other hand, cement production causes environmental pollution. If natural cementitious materials such as zeolite, which have abundant resources in Iran, are used, it will be economical and help the environment. In this research, the use of rubber granule and zeolite as additives in the stabilization of sandy soils with cement is evaluated. For this purpose, uniaxial compressive strength test on samples with different amounts of cement 6, 8 and 10% relative to the dry weight of the sample and replacement percentages of 0, 10, 30, 50, 70 and 90 of zeolite relative to cement and replacement percentages 0, 2.5, 5, 7.5, 10 and 12.5 of rubber granules were carried out. The results show that rubber granules and zeolites increase the final strength and strainability of the samples. SEM imaging of the samples showed the cohesion and integrity of the stabilization due to the addition of zeolite and rubber granule. The best mixing composition in the present study is 7.5% rubber granule and 30% zeolite as a cement substitute.
