Miscer tradies ReBar or steel fiber for concrete foor for truck workshop
So I need to make the concrete floor inside a workshop and some people say I should use re bar, others say I should use steel fiber, other say both so Idk what is the most cost effective + best performance for this.
This will be a truck workshop, sort of, kind of like a MOT. So heavy vehicles will go on this.
The concrete will be 20cm ( 7.8 inches ) and we will be using B400 concrete.
I was thinking maybe just put rebar + steel fiber on the path where the trucks go and then the rest just leave it with steel fiber because there will be no heavy loads on the rest of the areas
And also, is there such a thing as 2 slices of rebar ? kind of like sandwich ?

Hire an engineer man. But usually you'd use rebar to hold the pad together structurally, and use fibers to stop superficial cracks.
When it comes your time to die, be not like those whose hearts are filled with the fear of death, so that when their time comes they weep and pray for a little more time to live their lives over again in a different way. Sing your death song and die like a hero going home.

Both, but if you can only do one, Rebar.

What do u think of putting rebar only on the tracks and then in the rest just concrete with fiber ?
one or two layers of rebar ?

Re-bar is the mainstay... you can use fiber to reinforce. Re-bar and a thick slab for heavy trucks for sure. Fiber is really unnecessary.

Why not both? Rebar for sure, but fiber additive is pretty damn cheap. They don't even sell it here without it blended in.

so after I watched some videos on youtube it made it clear how much rebar impacts the strength of the concrete so that is a must, I will also add the fiber.
Anything else I should take in consideration ?

I would be searching for drawings/specs of a similar building from a reputable company with high standards and try to mimic that
There are all kinds of variations even just within the world of rebar, in terms of how the bars are spaced and shaped and all that

Impossible to say without design constraints. Cohbc would be all over this
Get the typical and max weights of the intended trucks, calculate dead weight, determine expected temperature ranges, etc.
That should get you minimum tensile and compressive strength, then you can choose your concrete mix and reinforcement to meet those requirements, with a safety factor added.
generally speaking, rebar adds tensile strength to concrete, and fiber mesh adds impact and abrasion resistance (as well as tensile strength but much less I think). If you expect things will be dropping on the floor a lot, you will need to consider that in your design.

I'd go with Steel Fibras to go with my Muscle fibras. Rebar sounds too much like retard so that's a no from me chief.
