Project ID:	FHWA-PROJ-11-0001
Project Name:	Rapid Characterization of Alkali-Silica Reactivity (ASR) in Concrete
Status:	Active
Contact:	Last Name: Arnold First Name: Terry Telephone: 202-493-3305 E-mail: terry.arnold@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
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, 2013
Funding Amount:	$0.00
FHWA Program Name:	Alkali-Silica Reactivity
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.
Project Type:	Onsite
Background Information:	Data not yet available
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: The deliverables are two tests: (1) a rapid test method to detect alkali-silica reaction (ASR) gels in concrete, and (2) a test to screen the susceptibility of aggregate to alkali-silica reaction (ASR) attack. Audiences: Concrete industry, Pavement designers, Pavement engineers, State highway agencies Secondary Audiences: , Concrete producers, Portland cement concrete pavement (PCCP) contractors
