High-cycle fatigue cracks in concrete investigated by μCT tomography

This contribution deals with the analysis of fatigue damage in high-performance concrete (HPC) studied by three-point bending test. The concrete sample was tested with frequency of 10 Hz and it was exposed to a total number of load cycles 2 × 106. The internal structure and damage localization was studied by μCT tomography. Found locations of internal damage i.e., cracks, were discussed.
