摘要：

A model is presented to predict the water permeability of OPC paste from its pore structure. It is based on the General Effective Media (GEM) theory and considers the contributions of capillary pores and gel pores. The pore structure of cement paste was determined by mercury intrusion porosimetry (MIP). The water permeability of cement paste was measured by using the input method. The model is shown to apply to both low- and high-permeability cement paste. The calculated results are in good agreement with experimental results. (C) 2001 Elsevier Science Ltd.
