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.

Nov 08, 2012· Civil Engineering: Rebar per cubic meter in RCC, Rebar Density … Rebar Density in Concrete : … and can vary from about 60 kg/ m3 for rafts to 250 kg/ m3 for beams. … Civil Engineering / Rebar per cubic meter in RCC.

generally within 0.9 to 1.1 kg of chlorides per cubic meter of concrete11. The objective of this investigation was to study the corrosion inhibition of commercially available migrating corrosion inhibitors on steel rebar in three concrete densities.

Portland concrete, the basic ingredient of concrete, is a closely controlled chemical combination of calcium, silicon, aluminum, iron and small amounts of other ingredients to which gypsum is added in the final grinding process to regulate the setting time of the concrete.

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.

Properties of concrete - Wikipedia, the free encyclopedia,The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 The reinforcement is often steel, rebar (mesh, spiral, bars and …

cubic yards is a volume while a pound is a weight, the question is nonsensical An 80 bag of Quikrete is 0.6 cubic yards, so dividing 0.6 by 80 means that one pound of Quikret … e will make 0.0075 cubic yards of concrete.

Rebar is a steel bar or mesh of Rebar is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and hold the concrete in tension. Rebar's surface is often patterned to form a better bond with the concrete.

May 21, 2008· Sometimes for rough estimates, I just use a ball park estimate per cubic yard of concrete.

As a bridge construction contractor (years ago) I was always surprised at the consistency of the ratio of rebar (lb.) to concrete (cubic ...

Steel reinforcing bars, known as rebar, are most commonly used to provide structure and tension support in concrete structures. Rebar generally costs about $0.75 per foot with slight price variations for thinner or thicker sticks. Usually sold in 2-foot lengths, prices can range from $1.40 to $1.84.

It all depends on the type and sizes of the steel used. It also depends on the load that the concrete has to take at certain points. 7865kg is the weight of a cubic meter of steel.
