I remember talking to a guy who dismissed the long term viability concrete reinforced with fibrous material. This was some time ago and my recollection is hazy. He claimed that his company—which produced a ceramic like polymer-based material for exterior building surfaces— was superior because crystalline changes in the matrix presented sharp edges the overtime sliced or cut the fiber reinforcement, eventually degrading the material.

It seemed plausible to the kid I was at the time, so I thought I’d ask some questions in response to these claims:

Is that true, what I heard back then?

If it is true, could a similar process eventually breakdown this material?

I hate changes in the matrix...

Sorry, I can’t answer your questions. I’m not a scientist.

I can tell you about fiber reinforce concrete. Even after twenty-five years it is about five times as difficult to remove with a concrete breaker. Be there — done that.
