Fiber reinforced concrete composite properties, such as crack resistance, reinforcement and increase in toughness are dependent on the mechanical properties of the fiber, bonding properties of the fiber and matrix, as well as the quantity and distribution within the matrix of the fibers.
In relation to the elastic modulus, fibers are divided into two types, those where the elastic modulus of fibers is less than the elastic modulus of the matrix: ie. cellulose fiber, polypropylene fiber, polyacrylonitrile fiber, etc.; and those where the elastic modulus of fibers is greater than the elastic modulus of the matrix: ie. asbestos fibers, glass fiber, steel fiber, carbon fiber, aramid fiber, etc. Basalt fiber is a new material that has been increasingly used in recent years.
