摘要：

The moisture permeability of hardened cement paste is normaily not a constant, because ii 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. (C) 1997 Elsevier Science Ltd.
