In a concrete slab where should steel reinforcing rods be embedded in slab?

A conventional slab will have two bars side by side near the top and bottom of each beam and a 16" grid across the entire top of the slab. Can't help you with a post tention... they are inventing new ways to take steel out of them every day.

Who was the first engineer to put reinforcing steel with concrete?
François Coignet in France
Why steel is called rebar?
It's simply hardened steel that's been cast in long rods. It's used as reinforcing when pouring concrete to increase the strwength - especially in road construction or building foundations.
How much weight can a 5 concrete slab hold?
The strength will vary depending on the type of concrete, the base, and the presence or absence of steel or fiberglass reinforcing.
What is Reinforced cement concrete-RCC?
Concrete is very strong in compression but weak in tension. RCC is concrete with reinforcing steel bars in it. Steel is a really good material in tension. Steel carries the tensile load and thus RCC is strong in tension too. However, designers still try to ensure concrete is in compression wherever possible.
What is the difference between reinforced concrete and pre stressed concrete?
Reinforced concrete has reinforcing bars (called rebar) simply embedded in the pour. With prestressed concrete, reinforcing rods or cables are stretched (stressed) and then the concrete is poured around them. After the concrete hardens, the tension on the reinforcing members compresses the concrete, making it more resistant to failure where poor soil conditions or severe loads exist.Prestressed construction is usually done in-plant because of the equipment involved, and the completed assembly shipped to the site for installation.A similar method, called post-tension, is usually done on site, and involves the tensioning of reinforcing cables after the slab is poured, using a special hydraulic jack.
What is one of the things you are trying to accomplish when consoliating concrete?
ensure concrete bonding around the reinforcing steel
What were the materials used to build the itaipu dam?
concrete, probably with steel reinforcing

How much does reinforced concrete cost?
Concrete is usually reinforced by adding steel. The cost of reinforcing concrete depends with the given area under which the steel is placed to reinforce it.

How do you estimate the placing of rebars?
The placement of steel reinforcing is dependent on the requirements of the strength and load-bearing of the concrete. A structural engineer should be contacted in this regard.
When does plain concrete become reinforced?
Reinforced concrete has steel bars embedded in it. It is also called re-barred concrete.
At what depth should the reinforcing be placed in a concrete garage floor supported by a concrete wall on all four sides and poured on compacted fill?
Steel re-inforcing in concrete should always be placed 1/3 of the depth from the bottom. A 6" thick slab would have the steel placed 2" off the bottom.
What are concrete beams for?
As I would interpret the question, I would refer to the nature of reinforcing to be placed within the concrete. Often in large beams, the reinforcing steel may be made up separately in "cages" and set in place for the concrete pour. The reinforcing may be comprised of shear, bending, torsional, and specialized support components.
Should you use steel reinforcing for sidewalks?
Best answer, there can be. In some concrete road applications, rebar web is used. Not all roadbeds are steel reinforced though. This is more common in newer bridge constructions.
