This paper presents the identification some principal fracture parameters of concretes by experiment and simulation on notched beam in bending. The comparison between experimental and simulation results allows to determinate the Critical stress intensity factors KIC, fracture energy Gf and characteristic lengths of fracture process zone (FPZ) lch of 6 class of concrete with the compression resistance varying from 20 MPa to 50 MPa. These are important parameter in the model for predicting the timelife of concrete structure exposed in coastal area.
