Resumo: Self-compacting concrete (SCC), with its important and main characteristic of not needing mechanical assistance for its densification, gives the construction more durable structures. This technology applied to concrete requires a large amount of fines in its composition, in order to meet the requirements of workability in the fresh state. For the SCC formulations, the residue from the processing of ornamental rocks (RPOR), the stone residue Cariri (SRC) and the concrete crushing residue (CCR) was selected. Using the methodology of Gomes (2002) for the dosage of SCC, the study of self-compacting mortar was carried out, using the tests with the Marsh cone and the Kantro cone to achieve the optimum percentage of superplasticizer and the appropriate amount of residue in the composition of the strokes, subsequently defining the best granulometric packing between the aggregates and the content of paste necessary for the concrete to be classified as SCC. The contents of addition of the residues were of 50% on the cement mass, being verified the properties in the fresh state through the spreading, ring J, funnel V and L-box tests. Subsequently, cylindrical specimens with dimensions of 10 cm x 20 cm were molded for resistance to axial compression at 28 days. Finally, water absorption tests were carried out by immersion and capillarity. The results showed the potential for application of residues in the production of SCC
