How much quantity of steel required for 1m3 concrete?

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

  1. For Foundation :- 0.5 to 0.8 % steel are required

Let we take minimum 0.5 % of steel is required on 1 m3 concrete

Then quantity of steel. = (0.5/100)×1× 7850

= 39.25 kg

7850 = density of steel

If we take maximum 0.8% steel is required

Then quantity of steel is = (0.8/100)× 7850

= 62.8 kg

2. For column :- 0.8 – 6 % of steel required

For minimum 0.8 %. = (0.8/100)×7850

= 62.8 kg

For maximum 6% = (6/100)× 7850

= 471 kg

3. For Beam :- 1- 2 %

For minimum 1% = (1/100) ×7850

= 78.5 kg

For maximum 2 % = (2/100) × 7850

= 157 kg

4. Slab and lintel :- 0.7 – 1.0 %

For minimum :- (0.7/100)× 7850

= 54.95 kg

For maximum 1% :- (1/100)× 7850

= 78.5 kg

Overall we assume Average 2.5 % of steel required in 1 m3 concrete work

Then = (2.5/100) × 1 ×7850

= 196.25 kg Approx 200 kg steel

1m3 = 200 kg steel

1m3 = 2 Quintal steel required
