If you make concrete with CFS 100-2 steel fibers at 70 pcy (pounds per cubic yard), you get, on average, 12 fibers in each cubic inch of concrete. No microcrack can go more than a fraction of an inch without running into a fiber.
A density of 145 pounds per cubic foot is a reasonable approximation for any commonly used concrete recipe. Reinforced concrete has steel bars called rebar inserted into it. Steel has a much higher density than concrete, which causes reinforced concrete to have a higher density.

Method 1: You can make a rough estimate by using thumb rule that about 80 kg of rebar is required per cum. of slab.So if slab size is say 10m x 10m x 0.2m. Concrete = 10 x 10 x 0.2 = 20 cum. Therefore, Rebar = 80 kg x 20 = 1600 kg = 1.6 MT. Method 2: Another thumb rule can be used that 1% steel by volume of slab. So for above slab, volume = 20 cum.
frostryan's formula essentially says that rebar is 4.4% by volume (or given a prismatic section, this is the steel area as a percent of gross area of section). If you subscribe to a unit-weight-of-reinforced-concrete formulation such as frostryan's, a bunch of algebra yields the following:
Reinforcement Estimates Typical average weight of reinforcement (kg/m3) in concrete building elements. The below figures are for guideline only and may vary for different projects.
Most concrete includes some type of reinforcement, such as rebar, wire mesh, plastic mesh, or fiber added to the concrete mix to increase strength and crack-resistance. Standard reinforcing materials can add approximately $0.18 cents per square foot.

Rebar in a Wall: This lets the user enter the dimensions of a wall and rebar specifications and computes the length and weight of rebar, the volume of concrete, and/or the surface area of the forms for a concrete wall.
The ratio of steel to concrete is 100:130 for 1 cubic meter. The ratio means that for every 130 kg of concrete, 100 kg of steel is needed to support the structure. This is a rule of thumb in civil engineering that must be observed at all times, as failure to observe it …
To calculate the quantity of reinforcing steel, known as rebar, for a rectangular concrete slab you need to measure the longitudinal and latitudinal length of the rectangle and either use a manual formula or construction calculator to determine the total linear footage of rebar required.
