| Roadmap/Focus area(s): | Infrastructure Research and Technology Strategic Plan and Roadmap | |
| Project Description: | This project will use Raman spectroscopy to develop a rapid method to identify alkali-silica reaction (ASR) gels in concrete. | |
| Goals: | The key project objective is to develop a rapid method to identify the presence of alkali-silica reaction (ASR) gels in concrete. No reliable test exists to detect the presence of ASR gels in existing structures. If the research is successful, Raman spectroscopy is a very suitable and easy technique for field use. | |
| Product Type: | Draft standard, specifications, or guidelines Research report | |
| Test Methodology: | The use of Raman spectroscopy to develop a rapid test method. | |
| Expected Benefits: | A rapid, reliable test that can be used in the field to detect alkali-silica reaction (ASR) gels in existing concrete structures. | |
| Deliverables: | Name: Test Method Product Type(s): Research report, Draft standard, specifications, or guidelines Description: A rapid test method to detect alkali-silica reactivity (ASR) gels in concrete. | |
