The use of mercury intrusion porosimetry or helium porosity to predict the moisture transport properties of hardened cement paste
The moisture permeability of hardened cement paste is normally not a constant, because it depends on both the porosity and the relative humidity (RH) in the pores of the cement paste when RH exceeds approximately 60 to 70%. The measured results show a strong relationship between the porosity of the cement paste and the moisture permeability.
