The paper introduces the basic fracture mechanics parameters of advanced building material - cement-based composites with various types of fibres, prepared as high performance concrete/mortar developed by ZPSV, a.s. company for production of thin-walled panels/elements. To this end three-point bend specimens with starting notch were prepared and tested under static (load-deflection diagram, effective fracture toughness) and cyclic loading (fatigue parameter -Wohler curve). The experimentally obtained results of cement-based composites are compared and the suitability of these types composites for its application are discussed.
