How much is the common Weight of Reinforcement in Kg/m³ for Beams?

Below mention quantities my own calculation in my current project.

 

 

Column and Roof Beams 181.42 kg/m3 Roof Slabs (240mm thick) 158.9 kg/m3 Small Bases (below3m3) 89.06 kg/m3 Grade Beams 206.94 kg/m3 Medium Bases (between10-20m3) 144.03 kg/m3 Retaining Wall 69.25 kg/m3 Ground Floor Slab (240mm thick) 67.09 kg/m3 Area Paving (100mm thick) 69.65 kg/m3 Duct Bank 59.76 kg/m3 Sleeper Pedestals 71.62 kg/m3 Building Walls (300mm thick) 157.63 kg/m3

if u r talking about density of steel then it is7850 kg/m3 and weight of reinforcement over concrete changes as per design and it varies according to type of constuction.

 

 

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

Hi., Actually what is your % steel by volume of Concrete.. Please tell me sir.

Approximately the Ratio of Steel for Beams is 160 kg/m3

reinforcement weight is 7850kg/m3

common weight of reinforcement is 150 kg/m3.

Footing - 80 kg/cumeccolumn - 160 kg/ cumecBeam - 110 kg/ cumecslab - 80 kg / cumec

average 120 kg/m3 in beam and slab

Originally it is depends on the design..it may be vary 105 kg/cum to 160 kg/cum.It will be less for Plinth beam as compared to floor beam.
