How much is the common Weight of Reinforcement in Kg/m³ .

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 is110-125 kg/m3. I hope this information useful for you. Thanks Andi
