Small Angle X-Ray and Neutron Scattering with Applications to Geomaterials provides new techniques for analysis of geomaterials, which is of great significance for human, because geomaterials are related to earthquake, resource development, underground spaces, carbon dioxide storage, etc. It is widely accepted that the microstructure of geomaterials has a significant influence on their macroscopic response. Various techniques have been employed to characterize the microstructure in geomaterials. Small angle scattering of X-ray and neutron are relatively new techniques that can be applied to obtain the nano-scale 3D structure in geomaterials. Small Angle X-Ray and Neutron Scattering with Applications to Geomaterials introduces the fundamental theory of small angle X-ray and neutron scattering. Next, the book covers pore accessibility characterization for natural rocks from four aspects: quantitative evaluation of pore structure heterogeneity and anisotropy; quantification of pore modification in coals due to pulverization; estimation and modeling of coal pore accessibility; and nanoscale coal deformation and alteration of porosity and pore orientation under uniaxial compression. Thirdly, interactions between pore structures and fluid behaviors in geomaterials are introduced. Finally, connections between small-angle scattering and other techniques (NMR cryoporometry, Transmission Electron Microscopy and synchrotron radiation SAXS and nano-CT) are described.
