PMSS Project Details


Project ID:FHWA-PROJ-11-0001
Project Name: Rapid Characterization of Alkali-Silica Reactivity (ASR) in Concrete
Status: Active
Last Name:Arnold
First Name:Terry
Office: Office of Infrastructure Research and Development
Team:Pavement Materials Team
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.
Laboratories: Chemistry Laboratory
Start Date: January 1, 2011
End Date: December 31, 2014
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.
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
