ADMIXTURE STALLS CORROSION

The corrosion problem and its correction at the Memphis International Airport's 500,000-square-foot, one-level concrete parking garage is described. A cost-effective corrosion prevention system using low permeability, silica fume concrete is described. The latter is portland cement concrete in which silica fume, an extremely fine pozzolan that fills in voids at microscopic levels, is included. Since silica fume has a high water demand, and the added water would negate its advantages, a high range, water reducing admixture, a superplasticizer, is added to provide workability while maintaining the desired water ratio. The parking structure will also incorporate epoxy-coated rebar for added corrosion resistance.
