Project detail
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 ASRĀ 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.
