How Much Steel is Required for 1m3 Concrete
Quantity of steel in concrete depending on the type of structure and load of the structure.
Then the Qty of steel = (0.5/100)×1× 7850 [ Density of Steel -7850 ]
Maximum 6%
Foundation
0.5 to 0.8 % of steel are required
Let's take at least 0.5% steel that is required in 1 m3 concrete
= 39.25 kg If we take Maximum 0.8% steel is required
Qty of steel = (0.8/100)× 7850
= 62.8 kg
Column
0.8 – 6 % of steel required
Minimum 0.8 %.
= (0.8/100)×7850
= 62.8 kg
= (6/100)× 7850
= 471 kg
3.
Beam
1- 2 %
Minimum 1%
= (1/100) ×7850
= 78.5 kg
Maximum 2 %
= (2/100) × 7850
= 157 kg
Slab and lintel
0.7 – 1.0 %
Minimum0.7 %
= (0.7/100)× 7850
= 54.95 kg
Maximum 1%
=(1/100)× 7850
= 78.5 kg
Overall we assume Average 2.5 % of steel required in 1 m3 concrete work
= (2.5/100) × 1 ×7850
= 196.25 kg ~ 200 kg steel
1m3
= 200 kg steel
1m3
= 2 Quintal steel required

How much-reinforced steel do I need for concrete?
The relative cross-sectional area of steel required for typical reinforced concrete is usually quite small and varies from 1% for most beams and slabs to 6% for some columns.
