Abstract
The purpose of this research is to quantify the amount and the diameters of connective pore structure and to study the effects on the mass transfer properties. Specifically, the diameters of “ink-bottled pore structure” were specified with a combination of the data from a mercury intrusion porosimeter and water vapor adsorption. As a result, ink-bottled pore diameters in hardened cement paste were 10nm-20nm. Also, the amounts of ink-bottled pore structures were decreased by the use of admixtures, and the mass transfers were inhibited. It was estimated that these results were related to the nano/meso-C-S-H structures.
