EVALUTION OF CHEMICALLY BOUND WATEWR OF WHITE CEMENT BY ~1H-NMR SOLID ECHO MEASUREMENT

摘要

Amount of chemically bound water, which is a result of cement hydration, is investigated with threemeasuring methods: thermal gravimetry analysis (TG), powder X-ray diffraction analysis withRietveld quantification (QXRD) and 1H-NMR relaxometry. For the measurement procedures of TGand QXRD analysis, ~1H-NMR relaxometry results showed well-agreement with those obtained byQXRD. As a result, ~1H-NMR relaxometry using solid-echo (quadrature) would be alternative tool toquantify the chemically bound water in white cement paste systems.
