Popis: | The dynamics of the hydration of a white cement with negligible iron content and of Portland cement with a considerable amount of iron has been studied by proton magnetic resonance. The presence of iron in Portland cement results in the protons close to the free electron spins of iron being out of resonance and their signal being suppressed. The evolution in time of the percentage of protons out of resonance in a Portland cement and the growth of the solid component have been determined as a function of hydration time. |
