摘要：

The resistivities of specimens of five different mortars were monitored during 18 weeks of exposure to sea-water. All specimens exhibited an increase in resistivity, 25mm thick specimens of the two more permeable mixes showing an increase equivalent to over 20mm of additional thickness after only 10 weeks of sea-water exposure. Measurement of pore solution resistivity, mercury intrusion porosimetry and surface examination and analysis were used to determine the mechanisms producing an increase in resistivity.
