| 摘要： | One hundred and fifty-six exposure slabs have been constructed with and without a variety of combinations of corrosion inhibiting admixtures and topically applied inhibitors. To accelerate corrosion one hundred and thirty-six of the slabs were constructed with concrete that surrounded the top mat of reinforcement with chloride contents of 3, 6, 10, and 15 lb/cubic yard (1.8, 3.5, 5.9, and 8.9 kg/cu m). This paper presents the results from measurements made on the slabs in 1998.5 after approximately 1 year of exposure. The measurements show that as the chloride ion content in the slabs increases, the macrocell current, macrocell potential, half-cell potential, and rate of corrosion increase and the resistance descreases. |
