The paper deals with the verification of the possibility of replacing natural aggregate with recycled aggregate concrete (RAC) in the production of precast concrete. In the practical experimental part, concrete mixtures with different proportions of recycled concrete are tested. The results shows that the use of recycled concrete as a substitute for aggregates is possible. However, the ratio of replaced aggregate is important because of the higher proportion of concrete recycled material would result in deterioration of the final properties of the concrete.
