Quantity Of Steel Required For 1 M3 Concrete


First of all, the quantity of steel does not depend on the concrete quantity instead, it depends on the type of structure and its dimension, loading condition, etc. However, if you need an approximate quantity you can use thumb rules. These thumb rules have been adopted based on the practice and experience of site work. To get the exact quantity it is always advised to go through design calculation.

Beam:

For Beam steel required 1% – 2%

Minimum percentage of steel =1.0%

∴Quantity of steel = (1.0/100) x 1 = 0.01 m³

Weight of steel = 0.01 x 7850 = 78.5 kg

Maximum percentage of steel = 2.0%

∴ Quantity of steel = (2.0/100) x 1 = 0.02 m³

Weight of steel = 0.02 x 7850 = 157 kg

Column:

For column steel required 0.8% – 6 %

Minimum percentage of steel =0.8%

∴Quantity of steel = (0.8/100) x 1 = 0.008 m³

Weight of steel = 0.008 x 7850 = 62.80 kg

Maximum percentage of steel = 6.0%

∴ Quantity of steel = (6.0/100) x 1 = 0.06 m³
Weight of steel = 0.06 x 7850 = 471 kg

Slab/Lintel:

For slab/lintel steel required 0.7% – 1 %

Minimum percentage of steel =0.7%

∴ Quantity of steel = (0.7/100) x 1 = 0.007 m³

Weight of steel = 0.007 x 7850 = 54.95 ≊ 55 kg

Maximum percentage of steel = 1.0%

∴ Quantity of steel = (1.0/100) x 1 = 0.01 m³

Weight of steel = 0.01 x 7850 = 78.5 kg 

Foundation:

For Foundation 0.5 to 0.8 % of steel is required.

Minimum percentage of steel =0.5%

∴ Quantity of steel = (0.5/100) x 1 = 0.005 m³

Weight of steel = 0.005 x 7850 = 39.25 kg

Maximum percentage of steel =0.8%

∴ Quantity of steel = (0.8/100) x 1 = 0.008 m³

Weight of steel = 0.008 x 7850 = 62.80 kg
