Nuclear magnetic resonance (NMR) —a powerful tool in cement and concrete research

The use of nuclear magnetic resonance (NMR) in cement and concrete research has been reviewed and the potential of the technique for future research has been elucidated. The most important nuclei Jor cement and concrete research are ¹H, ¹³C, ²⁷Al and ²⁹Si, and representative examples are given for each of them. NMR can be utilized to study the degree of hydration, the reactivity of pozzolanic materials, clinker composition, interaction of organic admixtures with cement minerals, the different states of water in concrete, etc.
