Advancements in Characterizing Fiber Distribution in Fiber-Reinforced Concrete Using X-ray Computed Tomography

Abstract The distribution of fibers within fiber-reinforced concrete significantly impacts its mechanical properties. X-ray computed tomography (CT) provides a distinctive and technically proficient method for examining fiber dispersion. This paper presents an exhaustive review of the methodologies used to characterize fiber distribution in concrete. It delves into the fundamental principles of X-ray CT and its application in studying fiber distribution, highlighting the current state of research. Additionally, the study explores the influence of fiber distribution and orientation on the failure mechanisms of concrete, offering insights that could guide future investigations in this domain. The paper concludes with a discussion on the potential of X-ray CT in evaluating fiber distribution and its implications for the mechanical properties of concrete, thereby setting the stage for further advancements in the field.
