The addition of steel fibres increased the flexural and ultimate capacity of the plain concrete wall panel. The improvement includes fracture toughness, helps to stop micro cracks forming macro-cracks, improves concrete ductility and its energy absorption capacity, as well as enhances overall durability. Fibre concrete mix is practical and economically attractive as it can be mixed, placed, and compacted using normal techniques.
