000003803 520__ $$2eng$$aThe paper presents the influence of the various notch depths for the range of starting notch width on a crack initiation in three-point bending specimens. These specimens are the most frequently used for fracture laboratory testing, especially of quasi-brittle cement-based composites. It is shown that the values of fracture toughness obtained from the tests of specimens with larger widths with various length of the starting notch can be overestimated.
