Since We are trying to calculate the unit weight of Steel Bar, the length of Steel Bar in the calculation would be 1 mtr or 1000 mm. Area of Steel Bar = ( X D^2)/4 Density of Steel Bar = 7850 Kgs/ = 7850/(1000X1000X1000) Cubic mm
minimum percentage of steel used is % for 1 cum . for exif we have to build a rcc slab having voloume 10 cum and to find steel used in this rcc in kg/m is density of steel =7850kg/cum and % of steel is used so simply it is the product of = for 1 cum now for 10 cum =1175kg. so for 10 cum rcc 1175 kg steel is used.
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...
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. Concrete building element. Weight of reinforcement in kg/m3. Bases Beams (lightly loaded)
Methods of Reinforcement Quantity Estimation: There are different methods for estimating the quantities of reinforcement; three methods of varying accuracy are: Method1 : Reinforcement Estimation (Thumb Rule Method) This simplest method is based on the type of structure and the volume of the reinforced concrete elements.
Must Read: How to calculate steel weight for Reinforcement. Example calculation: Steel quantity = Volume of Concrete x Density of Steel x % of Steel. For example, if a volume of concrete 1 cum for a slab. Approx Steel requirement = 1 x 7850 x 1% = Kg/Cum. Read: Bar bending Shape codes. Thumb rule for shuttering work
reinforcement. A concrete dam, cast integrally with the spec imen, allowed for the ponding of water or salt solution. The reinforcement consisted of No. 5 (No. 16) deformed bars. The top reinforcing bar consisted of conventional or galvanized steel; the bottom bars were pickled 2205 duplex stain less steel to prevent corrosion of these ...
This study evaluates the static and fatigue bond behavior in basalt fiberreinforced polymer (BFRP) bars embedded in concrete. For bond behavior under a monotensile load, BFRP bars with four types of surface patterns (round, rectangular, crosswinding, and spiralwinding) were adopted, and 20 groups of rib parameters were introduced for roundtype BFRP bars.

We will calculate the required concrete volume for the above beam as, V = L x B x D = 3 x x = m 3. According to the thumb rule, the concrete wastage is 3%, the reinforcement for the above example may be 3% = m 3
As we all know, the reason behind using reinforcement in concrete. Recap – The concrete is strong against compressive force weak against tensile force. So we use reinforcement bars to increase its tensile strength. The reinforced concrete is used in construction because of excellent durability, workability high strength.
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. Typical ...
An ordinary person can estimate reinforcement as a lump sum. I see many people estimate reinforcement as a percentage of concrete volume. Such as 2% or % of concrete volume. But as a construction professional you shouldn''t estimate rebar quantity as a percent of concrete volume. You should estimate that as shown in the structural drawing.

Quantity of steel is not dependent on the volume of concrete, but on the structure where it is being used. Slabs: to %, Beams: 1% to 2%, Columns: 1% to 5% It may vary depending upon the loading condition as well For Example Lets take exampl...
The steel rebar is widely used as a tensioning tool to reinforce concrete structures. It helps to strengthen the concrete and hold it in a tensioned state as well as it carries the tensile loads of the structure. These elements of the structure are commonly supplied with the patterned surface, which mechanically forms a firm bond with the concrete.
A limited number of investigations have been carried out to assess the cyclic bond behaviour of reinforcing steel bars in underwater concrete (UWC). An experimental campaign with 57 pullout specimens was undertaken, testing one mixture previously developed and characterized to be used in a cablestayed bridge project.

According calculation! Or do you want to know miniamum value? It should be according local norms. For example, according to SP (Russian norms for Nonprestressed Concrete Structures) minimum reinforcement area should be determined Asmin = mus * b * h0, where Asmin is the minimum area of reinforcing steel within the tensile zone, mus is the minimum reinforcement ratio, for bending mus .
