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.

We will calculate the required concrete volume for the above beam as, V = L x B x D = 3 x 0.2 x 0.5 = 0.3 m 3. According to the thumb rule, the concrete wastage is 3%, the reinforcement for the above example may be 3% = 0.009 m 3

Rebar calculator: quantities, weights, costs calculation ...

Dear Habeeb, It is depend how much MPA for the concrete, higher concrete MPA need high rebar also. As my experience for Fc32 is200 -250 kg/m3. For Fc40 is200 -400 kg/m3, but these are not efficience. Normally the ideal is kg/m3. I hope this information useful for you. Thanks Andi
