Behaviour of Concrete Panels Reinforced with Welded Wire Mesh and Fibres under Impact Loading
Centrally loaded round concrete panels reinforced with various combinations of fibers and welded wire meshes (WWM) were tested under impact loading. Two strength levels (50 MPa and 120 MPa) of the concrete matrix were studied. Both steel and synthetic fibers, at volume concentrations of 0.5% or 1.0%, were used. The impact strengths and fracture energies of the concrete panels were determined, as well as the strain-rate sensitivity of the various mixtures. Quite different behaviour was observed under impact loading, compared to that under static loading. It was concluded that a hybrid reinforcement system was more effective than any single type of reinforcement in mitigating the brittleness of the concrete.
