|Abstract:||The fracture energy of concrete produced with natural and recycled aggregates was investigated by conducting flexural tests on notched beams under a mid-span load. Test results indicate that recycled aggregate-concrete have a lower strength and stiffness when compared to conventional concrete. This may be due to the observed reduction in fracture energy caused by the presence of adhering old mortar in the recycled-aggregate particles. When proper mix adjustments were made it is possible to produce recycled-aggregate concrete of a desired quality.|
