Abstract: Scaling of concrete surfaces becomes a major durability issue on concrete roads, sidewalk pavements and bridge decks, especially in the case of a salt environment (i.e. because of de-icing salt) generated in cold climates. There are a number of factors affecting salt scaling resistance in concrete; this study has identified air entrainment, water/cement ratio, curing method and silica content as the significant parameters that affect concrete scaling resistance. An engineering robust design approach has been deployed to investigate the optimal condition that results in optimal salt scaling resistance. Parameter design has been performed using orthogonal arrays and lab experimentations to determine the best parameter combination to provide optimal scaling resistance. A comparison is made, using results of the lab experimentation and the predicted amount of scaled material at optimal conditions.
