->1T (Imaging quality)
-superconducting magnet (Homogeneity)
-Heavy, expensive, higher maintenance cost
High-Field NMR
-<1T (Less effect by ferromagnetic material )
-permanent magnet (no maintenance cost)
-Low weight, portable, inexpensive
Low-Field NMR
Low-Field NMR is more suitable for porous media analysis

T2 = relaxation time constant.
S = area of the pore surface.
V = volume of the pore.
2 = relaxation rate constant.
Pretreatment of water saturationAssuming pore shape is round
T2 is inverse proportional to the corresponding pore size

Hydration of Portland cement
Water status, water migration, unfrozen water content in frozen-thaw
Porosity, pore size distribution, permeability, saturation
The law of triaxial compression damage
Figuring out the distribution and phase change of water molecules in porous media is the crux of the matter.
