NEW ADDITIVE FOR IMPROVED DURABILITY OF CONCRETE AND PREVENTION OF REINFORCING CORROSION
This Innovations Deserving Exploratory Analysis (IDEA) project evaluated a class of organic compounds (salts of dicarboxylic acids) as additives for concrete that may improve its durability against freezing and thawing and reinforcement corrosion. Results showed an adverse effect of the admixtures on concrete workability and compressive strength, but acceptable freeze-thaw resistance. The concept is not successful for application as proposed.
