众所周知，混凝土的孔结构对其物理性能有很大的影响。因此，我们开发了一种技术，因为正确地清除它的孔隙结构的可视化。然而，这种可视化仅限于标本切片的二维成像。因此，在这项研究中，我们开发了一种技术，用于重建所获得的2D图像的孔隙结构成3D形式，通过堆叠它们。利用该图像，阐明了水渗透率与孔隙连通性之间的关系，并清楚地表明孔隙连通性强烈影响水渗透率。
It is widely known that the pore structure of concrete strongly influences its physical properties. Therefore, we developed a technique for the visualization of the pore structure because of clearing it correctly. However, this visualization is limited to two-dimensional imaging for sections of the specimen. As a result, in this study, we developed a technique for reconstructing the acquired 2D images of the pore structure into 3D form by stacking them. By using this image, the relationship between water permeability and pore connectivity was clarified, and it was shown clearly that the pore connectivity strongly affects the water permeability.
