What is it about?
Many people are beginning to use rapid electrical tests to test properties of concrete related to durability. This paper relates the formation factor (derived from a rapid electrical test) to both RCPT values and chloride diffusion. While specifications will be refined in the coming years the framework suggested has great potential for implementation due to its ease of use and power.

Why is it important?
While electrically based tests have been used for approximately a century, this work illustrates the relationship between the formation factor, a fundamental property which is related to ionic transport, with alternative tests and simple service life predictions. It discusses the framework adopted by AASHTO to move in this direction.
Perspectives
It was a great pleasure to write this with the co-authors. This article is one in a series that is really starting to look at concrete specifications in a new and exciting way to better consider address durability.
