To reduce the environmental impact of traditional lightweight concrete (TLC), porous aggregates can be substituted by rubber granulates. The mechanical properties of such rubber lightweight concrete (RLC) are investigated and compared with those of TLC made with expanded clay aggregates. Uniaxial compression and three point bending tests were performed for assessing the mechanical and ecological performances of the two mixtures, containing or not plastic fibers. As a result, when compressive strength is the functional unit of the analyses, TLC performs better than RLC. Conversely, fiber-reinforced RLC is the best solution when flexural strength and structural ductility are the required performances.
