Fiber distribution is an important factor affecting the workability and mechanical properties of fiber reinforced concrete. It reviews the characterization methods,theoretical derivation and control methods of fiber distribution in fiber reinforced concrete. First, experimental characterization methods of fiber distribution are described in details through indirect test and direct test; the advantages and disadvantages,the applicable scope of each method are analyzed. Second,theoretical derivation and prediction methods of fiber in random state and real situation are reviewed. Last,influence and control methods of fiber distribution are described,and the existed problems to be solved in the further study of fiber distribution are proposed.
