PROTECTION AGAINST CORROSION OF REINFORCING BARS USING HIGH-STRENGTH CONCRETE . PROTECTION OF CONCRETE. PROCEEDINGS OF THE INTERNATIONAL CONFERENCE HELD AT THE UNIVERSITY OF DUNDEE, SEPTEMBER 11-13, 1990

The paper mainly discussed the relationship between crack width and corrosion of bars. High-strength concrete was examined so as to prevent corrosion of bars. Accelerated test of duration from 1 week to 2 years was adopted. Main test results were as follows: (1) the corroded area showed the quantitative tendency with corroded length; (2) the high-strength member had clear relationship between crack and corrosion compared to normal strength concrete members; (3) there was no clear tendency between crack width and corrosion, but corrosion tended to become deeper and larger over the range of crack width 0.2 mm-0.25 mm, and (4) high-strength concrete contained less chloride compared to normal strength concrete.
