In this paper, the mechanisms of formation and propagation of fracture process zone (FPZ) of concrete are elaborated. According to the tension softening character, a banding microcrack model (BMM) has been developed to describe the innate characteristic and pattern of FPZ. By using BMM, the size of FPZ can be quantitatively calculated. The calculated results are compared with the experimental measurements of other researchers.
