Load capacity and behavior of fiber-reinforced concrete slabs: A review Available to Purchase

Concrete has become one of the most extensively used construction materials in a wide range of architectural buildings. Tension zone cracking is caused by concrete’s strength in compression but weakness in tension. The use of fiber-reinforced concrete in slab constrctusion has been increasing as a solution to this problem and to overcome such defect. Steel fibers can improve the load-carrying capacity of slabs assessed in shear and flexure, according to the literature review, especially when the slab thickness is controlled or reduced. The flexural behavior of FRC under cyclic stress is heavily influenced by fiber orientation, and by increasing fiber content, the absorbed energy of FRC under cyclic loading increases considerably, although the aspect ratio has only a little impact. The fracture pattern of slab specimens subjected to repetitive stress was remarkably identical to that of specimens subjected to static load, however as the number of loading cycles rose, more cracks formed and expanded.
