Study of steel fiber distribution patterns of steel fiber reinforced concrete: an overview

Previous studies on Steel Fiber Reinforced Concrete (SFRC) have focused on steel fiber distribution and mechanical properties of plastic, while less attention has been directed to the interrelated workability/flowability of fresh concrete. This paper the current knowledge on the factors influencing fiber performance including factors such as the concrete matrix, characteristics of the steel fiber, volume fraction of steel fiber, workability of fresh SFRC, casting methodology, boundary condition on the steel fiber distributions patterns and the relationship of steel fiber distribution patterns and mechanical properties of SFRC. The paper also identifies some potential issues concerning the effects of workability of fresh concrete on those properties.
