Original Abstract

3D laser scanning is a powerfull tool that digitally captures the shape of physical objects using a laser light crosses. In this work, the 3D laser scanning technology is used for the 3D shape capture of specially designed specimens. These specimens previously made of ne-grained cement-based composite of the nominal dimensions 40×40×160 mm with inclusion in the shape of prisms with nominal dimensions of 8×8×40 mm were provided with an initial central edge notch and tested in the threee-point bending conguration. The aim of this paper is to study the macrostructure of fracture surfaces via 3D scanning technology, verify the designed notch depth and evaluate the fracture toughness based on the measured notch depth and specimen height. The results indicate that the measured notch depth is lower than the designed one thus the differences between fracture toughness calculated for designed notch depth and for the measured one is approximately 10 %. In addition, the fracture toughness is overestimated when considering the design values.
