Construction of Civil works with out Cement & Reinforcement steel ia an unimaginable issue. Let us see about the rebar.
Rebar (short for reinforcing bar) is mild steel rod that comes in various thickness. Rebar is usually manufactured with deformations and the rebar is not perfectly round. The rebar is typically "textured" i.e. ribbed. That means that it is not smooth and therefore will grip better.
Rebar is also known as reinforcing steel, reinforcement rod, rerod, or a deformed bar, is a common steel bar,In Australia, it is colloquially known as reo.These bars are produced in sizes from 4 mm to 50 mm in diameter.
Above weights are as per clause 5.2 of IS 1786 - 1985.
For any steel reinforcement bar, weight per running meter is equal to d^2/162 Kg [(d X d )/162], where d is diameter of the bar in mm.
For example, 10 mm diameter bar will weigh 10x10/162 = 0.617 Kg/m.
