Time to Corrosion of Reinforcing Steel in Concrete Containing Calcium Nitrite
In 1996, the Florida Department of Transportation received 18 slabs from the Federal Highway Administration. These slabs were cast in 1980 using predetermined amounts of calcium nitrite in chloride-contaminated reinforced concrete. These specimens were compared to reinforced slabs with no admixed calcium nitrite. The upper and lower steel mats were connected and remained connected until 1996. Various tests were conducted on these slabs until June 1987, after which all testing terminated and the slabs remained outdoors. In 1996, the upper and lower reinforcing mats were disconnected. Prior to commencement of testing, the slabs were conditioned with water daily for two weeks. At the conclusion of testing, the slabs were conditioned with water daily for two weeks. At the conclusion of all nondestructive testing, the slabs were autopsied to assess the condition of the reinforcing steel. The findings of the study seem to indicate that calcium nitrite is effective in slowing the onset of corrosion in chloride-contaminated reinforced concrete as long was the ration of chloride to nitrite does not exceed 0.9.
