->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

Micro pores

Meso pores

Macro pores

The whole structure


Step 1Get original data

Time –domain curve

Signal amplitude changes over time

Step 2Fourier transformation

relaxation time domain

Higher peak implies higher concentration

Step 3Pore size distribution

Distribution frequency over pore size in

diameter


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.

NMR techniques: Explain Macrophenomenon from Micro perspective.
