No. There are plenty of complete driveways with no steel. Assuming you are refering to flatwork and not an actual building foundation.

What is the maximum aggregate size allowed in concrete slab that is 6inches thick?
2" based strictly on the slab thickness. However, it may be governed by form spacing, rebar spacing or rebar clearance to the forms.
Do you need to use wire mesh or rebar if im having fibermesh mixed with my concrete?
You still need rebar, unless you are filling a drop in an existing slab that already has steel in it.
How many pounds of rebar are in a typical concrete slab on grade?
There is no way to answer without a design and the square footage.
How much does 8 mm rebar in kg?
8mm rebar weighs 0.395kg/m
How stirrups are fixed in Reinforcement for concrete slab?
I assume they would be tied using tie-wire to the rest of the rebar cage.

Lenghts and spaces of a rebar in a slab?
varies depending on load to be put on slab, local codes, lots of variables. Check with bldg. dept., better yet a structural engineer.

How much rebar do you need for 10 x 15 slab?
If your peice of concrete does not have beams I consider that flatwork. So in flatwork with 3/8 rebar (#3) on 16" centers, for the 15 foot side you will have 8 pieces x 15' long. On the 10' side you will need 12 pieces x 10'. (6 bars cut in half) In all you will need 14 #3 x 20'
Why do all concrete slabs need rebar?
When the slab is loaded and force applied to it, the top of the slab directly under the load will be put in compression. However at the bottom of the slab. the concrete will pull itself in tension. Put the ends of your fingers together than flex your wrist up. You will feel the pressure at the top of your fingertips and you will see a gap open at the bottom. That is what is happening in a slab. Concrete is strong in compression, poor in tension. Rebar, or steel, is the opposite. By combining the two, you develop a product that is superior and complimentary to the strengths and weaknesses of the individual materials.
How do you patch or seal an exposed rebar post tension cable in foundation slab?
Rebar and Post Tension cable (PT) are two entirely different items. Rebar is the static steel bars placed in the concrete while the PT are high tensile strength cables that were placed in concrete than stressed under hydraulic jacking to a tension generally around 2500 to 3500 psi. As a result, the situations for repair are different. The exposed rebar can be cleaned and patched through approved methods. However the PT should be looked at by a professional as it is an integral part of the structure and, as mentioned before, is under tensioned stress. If the exposed rebar is in a PT slab, caution should be used and a professional consulted as well, due the rebar being integrated with the PT.
How thick is 3 rebar?
3/8" in diameter.
What is the nominal diameter of a number 8 rebar?
diameter 16
How thick should you pour your cement slab?
As a guideline, 4 inches thick, but it would depend on what is going to be sitting on top of it. You may need thicker and/or to reinforce it with rebar.
