Moisture is one of the major deterioration factors of concrete. In this study, the capillary absorption process, which is one of the major transportation mechanism in cement paste, is non-destructively investigated by using X-ray computed tomography (XCT). A novel image processing procedure is proposed to correct the XCT image artifacts and calibrate the results of different measurements. The proposed image processing procedure allows for 3D visualization of the absorption process and additional information can be obtained, including the height of the water absorption front and the water content gradient.

基于X射线计算机断层扫描的胶凝材料毛细吸收过程可视化示踪。

水分是混凝土的主要劣化因素之一。在这项研究中，毛细吸收过程是水泥浆中的主要传输机制之一，通过使用X射线计算机断层扫描（XCT）进行了无损研究。提出了一种新颖的图像处理程序来校正XCT图像伪影并校准不同测量的结果。所提出的图像处理程序可以对吸收过程进行3D可视化，并且可以获得其他信息，包括吸水前沿的高度和水含量梯度。
