Measuring Concrete Permeability with CHIP

Concrete infrastructure is a significant investment for State Highway Agencies. Because of this, these concrete structures must have a long service life. The permeability of concrete is critical in the durability of concrete.

The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 232 Measuring Concrete Permeability with CHIP seeks to improve an existing device called the CHIP (checking ion penetration). The CHIP can determine the permeability of concrete with a non-destructive, practical, fast, safe, and easy to use, which employs X-ray to image the penetration of outside salts into the concrete.
