“…In porous materials like concrete, the transversal relaxation depends strongly on how the water is bound in the pore system. Unbound water that can move freely, has a T2-relaxation time of about 2,000 ms [31] while water that is bound in the capillary pores and gel pores has a T2-relaxation time of about 0.5 ms -2 ms and 0.08 ms -0.12 ms, respectively [32].…”

“…When a magnetic field B0 is applied, the nuclei generate a magnetic moment Mz and precess with their Larmor frequency aligned to B0 [30]. In a state of equilibrium, the intensity of Mz is proportional to the number of hydrogen nuclei in the measuring volume and thus its water content [31]. When a second magnetic field B1 perpendicular to B0 is applied by radio-frequency (rf) irradiation, the atomic spins are tilted into the x-y-plane [30].…”

“…Erste Versuche wurden unternommen, beschleunigt carbonatisierte Strukturen auf Zementbasis mittels der Wasserstoffkernspinresonanz ( 1 H NMR) zu charakterisieren [10]. Die zerstörungsfreie Untersuchungsmethode hat bei der Untersuchung poröser Materialien und Polymere sehr gute Ergebnisse erzielt, was sie zu einem vielversprechenden Werkzeug für die In-situ-Beobachtung von Baumaterialien macht [11][12][13].…”
