Fiber-reinforced concrete (FRC) is gaining recognition for structural applications. It has demonstrated the ability to reduce crack spacing, width and deflection, while increasing stiffness and load-carrying capacity. These enhancements benefit the concrete's performance under service and ultimate limit states. However, the growing need for sustainable materials has driven the exploration of recycled plastics as an alternative to conventional reinforcement techniques. In view of this, this study presents an experimental investigation of the performance of FRC with recycled polypropylene in comparison to virgin one. Key parameters, such as crack propagation, post-cracking behavior and ultimate strength, are evaluated and compared.

Abstract
Fiber-reinforced concrete (FRC) is gaining recognition for structural applications. It has demonstrated the ability to reduce crack spacing, width and deflection, while increasing stiffness and load-carrying capacity. These enhancements benefit the concrete's performance under service and ultimate limit states. However, the growing need for sustainable materials has driven the exploration of recycled plastics as an alternative to conventional reinforcement techniques. In view of this, this study presents an experimental investigation of the performance of FRC with recycled polypropylene in comparison to virgin one. Key parameters, such as crack propagation, post-cracking behavior and ultimate strength, are evaluated and compared.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
