✦ Synopsis

The hydration process of beta-dicalcium silicate has been followed up to 1346 hours by the solid state nuclear magnetic resonance associated with the techniques of cross-polarization and magic-angle spinning. Our experimental results indicate substantial similarities between the hydration mechanisms of beta-dicalcium silicate ([3-C2S) and tricalcium silicate (C3S) and the overall composition and morphology of CSH formed from beta-dicalcium silicate and tricalcium silicate appear to be very similar. Also, we did not find the Q3 and Q4 components in the hydration products of beta-dicalcium silicate.
