Experimental research presented in this paper included testing of mineralogical-petrographic and physical-mechanical properties of natural dolerite aggregate (DI-1) and RCA, as well as their mixtures obtained by partial replacement of natural aggregate with RCA (15%, 30%, 45%, and 60%). The following conclusions can be made regarding the properties of used aggregates:.
