Team:   Pavement Materials Team [HRDI-10]
Program:   Exploratory Advanced Research
Laboratory:   Concrete Laboratory
Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   The project proposes to use nanotechnology to introduce engineered inclusions in cement to relieve tensile stresses and thereby reduce cracking in concrete.
Goals:   The key project objective is to increase understanding of and ability to improve properties of infrastructure materials.
Background Information:   This project is a response to the Exploratory Advanced Research Program broad agency announcement in the highway infrastructure focus area.
