Relationship between surface area of hardened cement and cement hydration was evaluated. Hydration process was evaluated by powder X-ray diffraction/Rietveld analysis, on the other hand, surface area of hardened cement paste is determined by water vapor adsorption isotherm and BET theory. Based on the experimental data, the surface area of hardened cement paste has strong correlation with the amount of C-S-H in hardened cement. The surface area by vapor adsorption is very sensitive to the sample preparation and therefore, correlation between surface and amount of C-S-H is different when the pre-drying condition is differed.
