The Reactive Powder Concrete (RPC) has compression strength in the range of 200 to 800 MPa. It is a durable material, with low permeability and appropriate for usage in lightweight structures and concrete strengthening. In this study, different concrete compositions were produced, each with water-cement ratio of 0.23, 0.25, 0.30, 0.35 and 0.40. The standard composition had the addition of crushed quartz. In the other compositions, it was replaced with waste from granite processing. Scanning Electron Microscopic (SEM) tests, compressive strength and Young’s modulus tests after 1, 3, 7 and 28 days of production and shear and flexural strength after 28 days of production were performed during the analysis. The results indicated that without thermal curing RPC does not reach the expected compressive strength. On the other hand, the addition of granite processing waste produced an improvement in compressive strength.
