Seems to be helping reduce hairline cracks in ferro-cement
I got this as an additive for making non-ferrous ferrocement. I am still just experimenting at this point, but this does seem to help reduce cracking. It is very challenging to keep thin applications of mortar moist while it cures, especially when it is in direct sun in the summer, so in theory the added fiber should help keep it from shrinking quite so much.

Thin 1” slab that held super well with vehicle traffic!
This stuff works. It makes a messy slab when wet, but a clean solid one once dry!
