• Abstract:

  Concrete is usually very requested in the field of civil construction, Its manufacturing process and application, in Brazil presents itself as the civil industry component that generates the most waste of environmental impact. Aiming at mitigating this environmental impact generated, studies have been developed relating the reuse of materials as a possible solution to solve this problem. In this fine line, the present work exposes an investigation on the  mechanical characteristics in the increment of the concrete with different concentrations of rigid polyurethane volume, to replace a portion of the coarse aggregate establishing relationships with the days of curing of the predefined concrete, with the aim of to produce structural concrete that meets current standards. The methodology adopted was the characterization of materials, granulometric verification, the slump of the concrete, the percentage of moisture acquired after curing the concrete and compressive strength. The data obtained showed very satisfactory results and with the potential to support the correct designation project for fillings and sealing of walls, partitions and panels, but unfeasible for structural purposes and intended for civil construction.
