The impact resistance and mechanical properties of the reinforced self-compacting concrete incorporating recycled CFRP fiber with different lengths and dosages

摘要

The present paper investigates the feasibility of using recycled CFRP fibers in self-compacting concrete. The fresh and hardened properties of the reinforced self-compacting concrete were assessed, considering different fiber volume fractions of 0.5%, 1%, 1.5%, and 2% along with different fiber lengths of 10, 20, and 30 mm. The fresh state properties of the reinforced mix compositions were evaluated in terms of flowability and viscosity. Moreover, the hardened properties of specimens were obtained by using the ultrasonic pulse velocity, compressive strength, flexural strength, and impact resistance. To characterize mechanical properties and impact resistance, 130 specimens were experimentally tested.
