Description:

Reinforcing steel in concrete is protected by a passive layer that is destroyed when exposed to chlorides. To maintain a bare deck, deicing salts that contain chlorides are used to remove the snow and ice. The chlorides penetrate the concrete, destroy the passive layer surrounding the reinforcing, and help initiate corrosion of the rebar. A computer program has been developed to calculate the chloride diffusion in concrete and to assist the engineer in analyzing existing bridge decks and future concrete repairs. The computer program calculates the diffusion coefficient, the applied surface chloride loads, and future chloride profiles based on chloride profiles from core tests. The program can evaluate different deck designs including changes in concrete cover, chloride loads, concrete type, sealer application and life, and other variables. The program is user-friendly and operates on a 386PC with a VGA screen.
