Steel required for 1m3 of concrete calculation is based on Thumb Rules, it is essential for any civil engineer, Site engineer or civil supervisor. They play and help a crucial role while taking quick decisions on site.

Steel is also known as reinforcement rebar or steel rods, which are embedded in concrete member to increase tensile strength of steel. It is used along with concrete in formation of structural member like column, beam, footing and slab of building.

The unit weight of steel is around 7850 kg/m3, or 78.5 kN/m3, or 7.85 g/cm^3, or 490 lbs/ft^3, or 13231 lbs/yd^3. The steel bars are majorly used as reinforcement to strengthen the concrete structures.

**How to calculate the quantity of steel per m³ of concrete?**

The quantity of steel reinforcement required for 1m3 of concrete depending on type of structure (slab, lintel, column, beam, or footing) and load of structure.

To calculate quantity of steel required per m3 of concrete structure, overall you would take on average 2.5 % of steel required per m3 concrete work. Then quantity of steel per m3 of concrete = (2.5/ 100) ×1 × 7850 = 196kg approx.

Calculation for quantity of steel required per m3 of concrete: 2.5% of 1m3 = 0.025m3, and we know that 1m3 steel weighs around 7,850 Kg, so, weight of 0.025m3 steel = 0.025 × 7850 = 196 kg, so, quantity of steel required for 1m3 concrete is about 196kg.

**How to calculate quantity of steel per m³ of concrete for beam**

To calculate quantity of steel required for beam per cubic meter of concrete, you would take 1% minimum and 2% maximum. Minimum quantity of steel = (1/100)×1× 7850 = 78.50kg, and maximum quantity of steel = (2/100)×1× 7850 = 157kg.

As per thumb rule and site analysis minimum quantity of steel required per m3 of concrete for beam is 1% and maximum is about 2%. Minimum quantity of steel required per m3 of concrete for beam is 78.50kg and maximum quantity of steel required for 1m3 concrete beam is 157kg.

Calculation for minimum quantity of steel required for beam per m3 of concrete: 1% of 1m3 = 0.01m3, and we know that 1m3 steel weighs around 7,850 Kg, so, weight of 0.01m3 steel = 0.01 × 7850 = 78.50 kg, so minimum quantity of steel required for 1m3 concrete beam is 78.50kg.

Calculation for maximum quantity of steel required for beam per m3 of concrete: 2% of 1m3 = 0.02m3, and we know that 1m3 steel weighs around 7,850 Kg, so, weight of 0.02m3 steel = 0.02 × 7850 = 157 kg, so maximum quantity of steel required for 1m3 concrete beam is 157kg.

**How to calculate quantity of steel per m³ of concrete for footing**

To calculate quantity of steel required for footing per cubic meter of concrete, you would take 0.5% minimum and 0.8% maximum. Minimum quantity of steel = (0.5/100)×1× 7850 = 40kg approx, and maximum quantity of steel = (0.8/100)×1× 7850 = 63kg approx.

As per thumb rule and site analysis minimum quantity of steel required per m3 of concrete for footing is 0.5% and maximum is about 0.8%. Minimum quantity of steel required per m3 of concrete for footing is 40kg and maximum quantity of steel required for 1m3 concrete footing is 63kg.

Calculation for minimum quantity of steel required for footing per m3 of concrete: 0.5% of 1m3 = 0.005m3, and we know that 1m3 steel weighs around 7,850 Kg, so, weight of 0.005m3 steel = 0.005 × 7850 = 40 kg, so minimum quantity of steel required for 1m3 concrete footing is 40kg.

Calculation for maximum quantity of steel required for footing per m3 of concrete: 0.8% of 1m3 = 0.008m3, and we know that 1m3 steel weighs around 7,850 Kg, so, weight of 0.008m3 steel = 0.008 × 7850 = 63 kg, so maximum quantity of steel required for 1m3 concrete footing is 63kg.

**How to calculate quantity of steel per m³ of concrete for slab & Lintel**

To calculate quantity of steel required for slab per cubic meter of concrete, you would take 0.7% minimum and 1% maximum. Minimum quantity of steel = (0.7/100)×1× 7850 = 55kg approx, and maximum quantity of steel = (1/100)×1× 7850 = 78.5kg approx.

As per thumb rule and site analysis minimum quantity of steel required per m3 of concrete for slab is 0.7% and maximum is about 1%. Minimum quantity of steel required per m3 of concrete for slab is 55kg and maximum quantity of steel required for 1m3 concrete slab is 78.5kg.

Calculation for minimum quantity of steel required for slab per m3 of concrete: 0.7% of 1m3 = 0.007m3, and we know that 1m3 steel weighs around 7,850 Kg, so, weight of 0.007m3 steel = 0.007 × 7850 = 55 kg, so minimum quantity of steel required for 1m3 concrete slab is 55kg.

Calculation for maximum quantity of steel required for slab per m3 of concrete: 1% of 1m3 = 0.01m3, and we know that 1m3 steel weighs around 7,850 Kg, so, weight of 0.01m3 steel = 0.01 × 7850 = 78.5 kg, so maximum quantity of steel required for 1m3 concrete slab is 78.5kg.

**How to calculate quantity of steel per m³ of concrete for column**

To calculate quantity of steel required for column per cubic meter of concrete, you would take 1% minimum and 6% maximum. Minimum quantity of steel = (1/100)×1× 7850 = 78.50kg approx, and maximum quantity of steel = (6/100)×1× 7850 = 471kg approx.

As per thumb rule and site analysis minimum quantity of steel required per m3 of concrete for column is 1% and maximum is about 6%. Minimum quantity of steel required per m3 of concrete for column is 78.50kg and maximum quantity of steel required for 1m3 concrete column is 471kg.

Calculation for minimum quantity of steel required for column per m3 of concrete: 1% of 1m3 = 0.01m3, and we know that 1m3 steel weighs around 7,850 Kg, so, weight of 0.01m3 steel = 0.01 × 7850 = 78.50 kg, so minimum quantity of steel required for 1m3 concrete column is 78.5kg.

Calculation for maximum quantity of steel required for column per m3 of concrete: 6% of 1m3 = 0.06m3, and we know that 1m3 steel weighs around 7,850 Kg, so, weight of 0.06m3 steel = 0.06 × 7850 = 471 kg, so maximum quantity of steel required for 1m3 concrete column is 471kg.
