Possible Application of Computed Tomography for Numerical Simulation of the Damage Mechanism of Cementitious Materials—A Method Review

Abstract

Modeling the meso-scale behavior of a material allows one to answer many problems in an inductive reasoning approach. By simulating the behavior of the sample, researchers can correct the overall behavior of the material. The purpose of this article was to gather the main information linking the issue of tomographic imaging to the modeling of damage mechanisms. This paper addresses the topic of meso-scale modeling of cementitious materials. The authors have mapped the interconnectedness of the issues of cementitious materials and X-ray computed tomography (µCT) according to the Web of Science database. The main interconnecting threads are indicated. The authors focused on the use of µCT. The theoretical basis for conducting tomographic measurements is presented. Reference was made to the basics of physics and mathematics in X-ray projection and data reconstruction. Tools and analyses for data processing are indicated. The benefits of in situ µCT are indicated with reference to the practical application of the method. In addition, the main developments of recent years in the most widely used computational methods for meso-scale models are presented.
