Themanagement of rubberwaste is of great importance for environmental protection, the economic aspect is important. The material recycling of rubber waste results in granulate with different fractions. It is successfully used e.g. in road construction to modify asphalt. Research is also being conducted into the use of rubber granules for the production of cement concrete. The article presents the results of tests of cement mortars with the addition of SBR rubber dust from recycled rubber waste from household appliances, car seals and industrial belt conveyors. The application of rubber dust in cement mortars causes a decrease in their compressive and tensile strength, a decrease in apparent density and an increase in absorbability with an increase in the amount of rubber dust. The increase in the amount of rubber makes the mortar less brittle as the relation between tensile strength and compressive strength increases.
