The work aimed to show that it is feasible to integrate ceramic waste from the construction industry and demolitions into the content of concrete recipes, as a partial replacement for natural aggregates in standard concrete recipes. The integration of these wastes into the composition of concrete is of particular importance because, on the one hand, we reduce the amount of waste resulting from the construction industry, and on the other hand, we achieve savings of raw materials used in the manufacture of concrete, coming from exhaustible natural resources. Compared to the standard C16/20 concrete recipe used as the control sample in the experimental recipe, the natural aggregates of size 4-8 mm were partially replaced by 50% ceramic waste. Various physical-mechanical tests were performed, such as determining the density of fresh concrete, determining the compressive strength of concrete containing ceramic waste compared to a standard concrete recipe containing natural aggregate. Following tests on experimental recipes, very good results were obtained in determining the compressive strength, which were similar to the test results on standard concrete recipes.
