Florida marine bridges are exposed to aggressive environments with high temperature, humidity and chloride exposure. Corrosion control guidelines for design at present emphasize the use of low permeability concrete by means of pozzolanic admixtures, high cementitious content, low water to cementitious ratio, and high clear concrete cover. Highlights of field evaluations are presented describing experience that led to discontinuing the use of epoxy coated rebar, verification of the adequate performance of newly formulated concretes, and assessment of the impact of cracking on durability. A brief update on corrosion issues in post tensioned systems is presented as well.
