Subject of this investigation is the in-situ evolution of pore volume and pore size distribution in Ytong (a porous concrete material) under increasing pressure with two different non-destructive analytical methods: Nuclear Magnetic Resonance (NMR) and X-ray Computed Tomography (CT). For both methods special strain devices to apply external pressure were constructed. The results from the two techniques yield complementary information on the pore size distribution and allows covering different pore size regions.

用无损方法对加载多孔混凝土进行原位孔径研究

本研究的主题是使用两种不同的非破坏性分析方法：核磁共振 (NMR) 和 X 射线计算机断层扫描 (X-ray Computed Tomography)，在不断增加的压力下原位演化 Ytong（一种多孔混凝土材料）的孔隙体积和孔径分布。 CT）。对于这两种方法，都构建了特殊的应变装置来施加外部压力。这两种技术的结果产生了关于孔径分布的互补信息，并允许覆盖不同的孔径区域。
