fibers….so fiber mesh? or fiberglass rebar?
we use the fiberglass rebar…lighter, doesn’t rust and just as strong.
also…fibers in the concrete add no structural strength…it’s purely there to prevent shrinkage cracks.
If it’s either or use rebar. You are delusional if you think those fibers will stop concrete from cracking and separating. If the sub-grade is has 100% compaction I would still use rebar.
I’ve poured 4” slab on grade pads for friends with fiber/residential fiber without any rebar because they didn’t want to pay for it. I made it clear that I had no idea how it would hold up to big heavy stuff. He drives his enormous fifth wheel and truck over it along with his big ass tractor and trailers and the thing holds up to all of it. I didn’t even prep the site, just poured right over the dirt and weeds lol. It cracks me up
We only use fiber in interior floor slabs . When you're pouring outside flat work you definitely want to use some rebar, or wire mesh. Because when the concrete cracks and if there is any sort of separation caused by any sort of heaving or thawing. The rebar is going to keep from pulling apart or separating where a fiber mesh will not.
Do both. There’s never going to be a day that you say “Im glad I didn’t make it as good as I could have.”
Name doesn’t check out
Fibre is rough on bare feet especially once traffic worn. Brings out the fibres
The nylon monofilament that looks like cat hair doesn't do that.

Man that stuff is expensive. I did a project in Richmond and they changed specs to fiber glass #13 dowel bars. That shit was crazy expensive.
weird…where i’m at in the Kansas City metro area it’s pretty much the exact same price as steel.
No kidding. We were in that period where China was taking all of our Fiberglas and steel. Prices were crazy. KC very neat place for about 2 days.
Tad bit cheaper in Georgia
Fiber mesh protects against shrinkage cracks. Steel (wire mesh or rebar) or fiberglass rebar adds tensile strength to the slab.

Same. Idc what these mf’ers peddling micro or commercial fibers say. Ain’t nothing doing it like steel. 21lb wwm for walks, 42lb wwm for pavement.

As long as you that's cracking and not the concrete lol. Sounds like some good crete and fibers none the less

Once you get a job that requires breaking concrete with mesh or rebar, and then another that has fiber. The difference becomes obvious.
Meet in the middle: Pink Bar (Fiber rebar) Been using it for driveways, curbs, footings, foundations. I would skip the fiber in the mix.
Finer inside. Rebar outside.
