Sažetak
Different types of fibers are used in a variety of cementitious materials to improve their properties. Uniformly distributed and aligned fibers are crucial to ensure the desired improvements. Experimental techniques for microstructural characterization of materials, such as micro-computed tomography, are critical to understanding the contribution of fibers to the behavior of composite materials. As a non- destructive method, micro-computed tomography (CT) has been used in medicine as a diagnostic imaging technique since the 1970s and is gradually finding application in other industries. The 3D view of the internal structure of the materials under investigation makes CT a valuable tool for the evaluation of fiber-reinforced composites. The actual fiber content, distribution and orientation of individual fibers can be easily determined and used to explain the behavior of composites. To date, research has focused mainly on steel fibers, whose high specific density facilitates the identification of fibers in the cement matrix. Synthetic fibers present a greater challenge to CT due to their low density and lack of conductivity. In this paper, the basic principles of X-ray computed tomography, its advantages and limitations are presented, focusing on the methods for detecting the distribution of synthetic fibers in cementitious composites.
