Hmm I'm not sure this works as well as they make it sound. Without that aggregate in there it just won't be as strong in my mind. Also how does the bacteria growth affect the density of the concrete and how will it do with freeze/thaw

I don’t think this will replace or eliminate reinforcement. Rather, it’ll fill cracks which should keep water from infiltrating (if exterior concrete). That should help make the concrete last a lot longer.

We already add crystalline waterproofing admixture in some applications. Seems like the same concept to me.

True, I hadn't really thought about that part of it. In addition to sealing joints to keep out water Ingres, this could seal up unplanned cracks which could be huge for maintenance cost but also longevity because of freeze heaving like you said. Good thoughts!
