EARLY AGE FRACTURE BEHAVIOR OF HYBRID FIBER-REINFORCED CONCRETE

Controlling and mitigating cracks in concrete is one of the main problems in construction engineering. In this work, improvement of crack resistance against thermal stress and shrinkage of the mass concrete at an early age were studied using a hybrid fiber reinforced concrete (FRC). The fibers used were steel and polypropylene fibers with lengths of 6, 12, and 30 mm. Physical properties as well as crack resistance capabilities of the hybrid FRC were evaluated. As a result of this research, a strain energy release rate, calculated by fracture mechanics, is proposed.
