Over the last 30 years, a variety of approaches have been taken to delay the start of corrosion of reinforcement in concrete. While short term and accelerated performance data is readily available in the literature, it is difficult to find long term laboratory data performed under control conditions. This report intends on filling that gap in the knowledge base of the performance of the various products evaluated.

The long term laboratory performance of specimens with 1.75 inches (4.4 cm) of concrete cover exposed to 3 wt% NaCl at 72° F (22 °C) and 64% humidity is presented. Specimens were made with corrosion inhibitors, concrete penetrant sealers, coated rebar, galvanized rebar, and supplementary cementitious materials of various types and quantities.

Keywords: High Performance Concrete, Corrosion Inhibitors, Galvanized, Rebar, Epoxy Coated, Supplementary Cementitious Materials, Fly Ash, Silica Fume, Super Fine Fly Ash
