The purpose of this investigation is to provide administrators and designers with factual data on which to base decisions as to the type of protection to provide for bridge decks constructed in corrosive environments. The specific study objective is to determine the relative time to corrosion of reinforcing steel embedded in concrete slabs that are fabricated from various mix designs and construction procedures and subject to periodic wetting with a 3 percent sodium chloride solution. Constructed and tested were 124 reinforced concrete slabs 4 by 5 by 0.5 ft. Data obtained from tests of the effect of portland cement concrete mix design, concrete cover over the reinforcing steel, and consolidation of the fresh plastic concrete are discussed in this paper. A brief description of slab fabrication and testing procedures is also presented.
