This paper introduces the basic fracture mechanics parameters of advanced building material – glass fibres rein-forced cement based composite and its fracture and fatigue behaviour is investigated. To this aim three–point bend (3PB) specimens with starting notch were prepared and tested under static (l–d diagram) and cyclic loading (Paris law and Wöhler curve). To evaluate the results, the finite element method was used for estimation of the corresponding values of stress intensity factor for the 3PB specimen used. The results obtained are compared with literature data.
