# How Much Steel is Required for 1m3 Concrete

Quantity of steel in concrete depending on the type of structure and load of the structure.

### 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

Then the Qty of steel  = (0.5/100)×1× 7850  [ Density of Steel -7850 ]

= 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

Maximum 6%
= (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.
