Chemical Solutions to Durability Studies

The state of Texas has been plagued by various durability-related issues in recent years, including deterioration from alkali-silica reaction, delayed ettringite formation, corrosion of reinforcing steel, and volume changes (plastic shrinkage, drying shrinkage, thermal effects, etc.), just to name a few. These durability-related issues, coupled with other factors, contribute to reductions in service life (e.g., service loads and defects). For many of these problems, fly ash (primarily Class F) has been the remedy of choice; however, with changes in fly ash quality and quantity spurred by new emissions standards, there is a major concern that fly ash will not be able to fill these needs in the long term. The goal of this project is to evaluate chemical alternatives to fly ash, such as the use of chemical admixtures aimed at specifically improving concrete durability.
