What is r in rebar?

Rebar (short for reinforcing bar), known when massed as reinforcing steel or reinforcement steel, is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension.

What is Schedule of bar?

Bar bending schedule or schedule of bars is a tabular representation of reinforcement bar. It is generally represented for each type of R.C.C work. Bar bending schedule generally describes the particulars of bars, shape of bending with sketches and total length and weight of the bars along with their numbers.

What is D in bar bending schedule?

Bar Bending Schedule :-

S.No.	Particulars
1.	Standard Length of the Steel Bar (Bars are sold at standard Length)
2.	Weight of Bar for length = 1m
Ex:	If length of bar is 12m with 10mm Dia then , Weight of bar = D2/162 Therefore for length 1m = 1m x D2/162 = 1 x 102/162 = 0.61 Kgs For length 12m = 12 x 102/162 = 7.40Kgs
