At this time Jack we have only tested it with conventional concrete. Like you; I also believe it would work well with the fibers added in the mix and our chemist says the same thing.
Winter salt is something that just accelerates the rusting of reinforcing steel in northern climates and that is something that we are very well aware of.
We have other testing lined up once we get the permeability results back including freeze / thawing and salt water exposure. We just have to take it one step at time.
Thanks for dropping by and sharing your thoughts, very much appreciated.
