In this context, the present study aimed to evaluate the influence of coarse aggregate type on the rheological and mechanical properties of SCC, comparing mixtures produced with crushed stone (size 0) and natural pebble, while keeping all other constituent materials constant. Fresh-state tests — Slump Flow, L-Box, U-Box, J-Ring, and V-Funnel — and hardened-state tests — compressive strength and splitting tensile strength at 7 and 14 days — were performed. Results showed that the mixture with pebble exhibited superior rheological performance, presenting higher flowability and lower resistance to movement, whereas the mixture with crushed stone achieved higher mechanical strength at all tested ages. Statistical analysis indicated good experimental repeatability and consistency with theoretical behavior expected for cementitious materials. It was concluded that the coarse aggregate type directly affects both workability and structural performance, highlighting the importance of proper aggregate selection according to project and execution requirements.Acesso AbertoConcreto autoadensávelAgregados graúdosReologiaResistência mecânicaSelf-compacting concreteCoarse aggregatesRheologyMechanical strengthCNPQ::ENGENHARIAS::ENGENHARIA CIVILTrabalho de Curso - Graduação - Monografia
