| Abstract: | In order to investigate the defect changes of cement mortar due to carbonation,X-ray computed tomography(XCT) was employed to quantitatively analyze three dimensional(3D) meso-defect volume distribution changes of cement mortar before and after carbonation.The high-resolution 3D images of microstructures and filtered defects were reconstructed by XCT VG Studio MAX 2.0 software.The meso-defect volume fractions and size distribution were analyzed based on 3D images via add-on modules of 3D defect analysis.The... |
