Hi Nori, I dont think perlite is available in commercial form in a
fibrous material.
If it is only available in a granular form I am familiar with from
horticulture, I doubt it would constitue a fibrous reinforcement.
Adherence between the cement and ganules is not the same mechanism as
embedding hi tensile strength fibers in the mix.
OR I could be as full of it as the christmas goose with this
analysis! :-)
