    The construction industry has had a significant impact on the environment due to the emission of greenhouse gases and the extraction of natural resources. Reinforced concrete, essential in construction, combines iron and cement, improving mechanical strength. In response, sustainable practices such as the recycling of construction materials have been promoted. This research analyzes the performance of reinforced concrete using recycled materials from construction and demolition waste, evaluating the feasibility of replacing natural coarse aggregate with recycled aggregate. Flexural tests were performed on reinforced concrete beams, comparing the mechanical properties of beams with natural and recycled aggregates. The beams with natural aggregate withstood a maximum load of 21.56 kN and presented a modulus of rupture of 5627.47 MPa, while the beams with recycled aggregate reached a maximum load of 19.62 kN and a modulus of rupture of 5120.80 MPa. The maximum displacement was 49.52 mm for beams with natural aggregate and 22.28 mm for those with recycled aggregate, showing greater ductility in the former. The recycling and reuse of materials in construction, in the production of new concrete with recycled aggregate, not only reduces the environmental impact and the demand for natural resources, but also makes it possible to contribute to the sustainable development objectives (Objective 11) in terms of innovation of materials and sustainable cities and communities. The implementation of an efficient sorting and recycling system is essential to reuse waste as raw material in the manufacture of new building materials, promoting a more sustainable construction.
