Default re: Castable Fibers

The stainless steel fibers are called melt extract fibers, even though they're steel. Other fibers used are added to the mix and are designed to burn away at about 160C leaving tiny holes where steam can escape. Maybe these are what was omitted.

Huh. Live and learn. Thanks for the info. It makes sense to use a metal fiber in refractory concrete: I'm told the needles are sharp, and have a tendency to poke holes in things like hands and gloves.

Yes they are sharp, but you learn to handle the mix carefully and it's not too bad. The worst is the cost of the things, because you need a fair amount.
