PMSS Project Details


Project ID:FHWA-PROJ-12-0025
Project Name: Performance Evaluation of Prestressing Strands for Concrete Bridges With Chloride Contaminated Grout
Status: Completed
Last Name:Ghasemi
First Name:Hamid
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:A research program will be conducted to obtain a preliminary estimate of a chloride threshold value for corrosion initiation for prestressing strands.
Laboratories: Coatings and Corrosion Laboratory
Nondestructive Evaluation (NDE) Laboratory
Start Date: February 1, 2012
End Date: February 1, 2015
Goals: The key project objective is to conduct research on prestressing strands grouted with samples of cement grout containing different levels of chloride to obtain a preliminary estimate of a chloride threshold value for corrosion initiation.
Test Methodology: Lab and field tests.
Expected Benefits:The expected benefit is the improvement of the knowledgebase pertaining to threshold values of chloride in grout for prestressing strands.
