In recent years,nuclear magnetic resonance has become an important technique for characterizing hy-dration process,non-chemical bound water and pore structure of cement-based materials.This paper briefly introduces fundamentals of nuclear magnetic resonance and several main parameters about low-field nuclear magnetic resonance, lists the application of low-field nuclear magnetic resonance in cement-based materials,which include hydration process,pore structure,moisture migration and diffusion et al.,and provide an outlook on the development trend and prospects of the low-field magnetic resonance applied in cement-based materials.
