Project ID:	FHWA-PROJ-09-0023
Project Name:	Accelerated Determination of Alkali-Silica Reaction Susceptibility During Concrete Prism Testing Through Nonlinear Resonance Ultrasonic Spectroscopy
Status:	Active
Contact:	Last Name: Virmani First Name: Paul Telephone: 202-493-3052 E-mail: paul.virmani@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Infrastructure Research and Development
Team:	Infrastructure Management Team
Roadmap/Focus area(s):	Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:	The objective of this study is to develop a reliable rapid Nondestructive Evaluation (NDE) technique for assessing and quantifying the alkali-silica reactivity (ASR) in aggregate and aggregate/paste combinations. The American Society for Testing and Materials (ASTM) C1293 test method is accurate, but it takes one to two years to complete. On the other hand, ASTM C 1260 is an accelerated laboratory test method, but its accuracy to predict field performance is not good.
Laboratories:	Not Applicable
Start Date:	July 31, 2009
End Date:	October 31, 2012
Funding Amount:	$321,000.00
FHWA Program Name:	Alkali-Silica Reactivity
Goals:	The key project objective is to develop an accelerated Nondestructive Evaluation (NDE) laboratory test method for evaluating concrete mixtures for alkali-silica reactivity (ASR).
