This paper is focused on investigation of the possibility of using recycled aggregate in concrete mixes instead of natural aggregate. Our research included the preparation of concrete mixtures with recycled aggregate of concrete and natural fine aggregate. It has been focused on evaluation of compressive strength of old and new concrete, granulometric distribution analysis of recycled concrete, density of new and old concrete, water permeability in concrete, and measuring of Ultrasonic Pulse
