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 alkali-silica reactions (ASRs) 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.
The key project objectives are to:
- Advance the fundamental understanding of an alkali-silica reaction (ASR).
- Develop a rapid and reliable test method to evaluate concrete mixture design to assess alkali-silica reaction (ASR) reactivity.
