Measurement of pore size distribution of hardened cement by thermoporometry

Abstract

Thermoporometry is watched as new analytical approach for characterizing pore structure. Hardened cement has 2nm to 200nm wide range of pore size distribution, and it is necessary to analyze melting or freezing behavior of water about -0.1oC. But it is difficult to measure correctly by DSC. This study discussed melting behavior of freeze water and cyclohexane in porous silica, and suggested how to measure pore size distribution of hardened cement as compared with Mercury Intrusion Porosimetry.
