Understanding the Alkali-Silica Reaction Mechanism and Developing Rapid and Reliable Laboratory Test Methods to Address ASR Reactivity of Concrete Mixture Design
Project Information
The goal of this project is to eliminate/reduce the deteriorating effects of alkali-silica reactions (ASRs) in highway concrete structures, even when exposed to adverse natural environments, by understanding ASR mechanisms and developing methodology to design concrete mix design resistant to alkali-silica reactions (ASRs) phenomenon. Another goal of this project is to develop an accelerated laboratory test method to replace the ASTM C 1260 test method, which takes one to two years to complete.
Goals
The key project objectives are to:
- Advance the fundamental understanding of an ASR.
- Develop a rapid and reliable test method to evaluate concrete mixture design to assess ASR reactivity.
- Infrastructure
- FY 2002-2022 / Infrastructure / Pavements and Materials
