How much quantity of steel required for 1m3 concrete?
Quantity of steel in concrete depending on type of structure and load of structure.
- 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
