PMSS Project Details

 

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
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.
Start Date: July 31, 2009
End Date: October 31, 2012
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).
Test Methodology: Nonlinear Resonance Ultrasonic Spectroscopy
Expected Benefits:The expected benefit is a rapid alkali-silica reactivity method to evaluate aggregate reactivity.
Deliverables:Name: Report
Product Type(s): Research report
Description: The product is equipment for alkali-silica reactivity (ASR) aggregate reactivity.
