Abstract

It is strongly needed to predict and reduce the amount of concrete shrinkage. Prediction of hardened cement paste needs the information of specific surface area, volumetric water, and bulk modulus when it is based on the theory of hydration pressure. For this purpose, it is important to evaluate the water vapor BET surface area and find the way to predict this value. In this study, the specific surface area of various cement paste was determined by water vapor adsorption isotherm and B.E.T theory and chemically bound water of hardened cement of those was determined by thermal gravity analysis. Based on these data, the unique relationship between chemically bound water at the state of 11%RH condition and BET specific surface is found regardless of cement types.
