How much quantity of steel required for 1m3 concrete

The quantity of steel required for 1 cubic meter of concrete depends on the type of structural element and the design specifications. As a general guideline, steel reinforcement is often used in concrete at around 1% to 2% of the concrete volume. This means for 1 cubic meter of concrete, you might use 80 to 160 kilograms of steel.

How much quantity of steel is required for 1m3 concrete, hi guys in this article we know about quantity of steel is required for 1m3 concrete. Actual Steel calculation is based on as per design but if design is not given then Steel calculation is based on Thumb Rule on experience basis.

Steel required for 1 M3 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.

Thumb rules help you in finding out the approximate quantity of steel in RCC structure and make solution easy using a simple mathematical formula and make smart decisions whenever needed.

But, while using these thumb rules, you must remember that the thumb rule never gives the exact or accurate results, you just have used them for approximate results.

How much is steel is required for 1m3 concrete not only based on quantity of concrete but it also depend on other factors, such common factors are discussed here. Quantity of steel required for 1 M3 concrete is based on following factors:-

1) Type of structure (Load Bearing/Framed)

2) Purpose of structure (Load depends on the utility)

3) Type of dia of Bar

4) Size height of column and length of beam (in terms of height, as requirement varies according to construction i.e. whether horizontal or vertical. )

5) Most important is foundation type(depends on soil bearing conditions)

For general residential building of ground floor house we have to calculate Steel quantity. We use different types of Thumb Rule for steel calculation all type of RCC structure footing, column, beam & RCC slab.

How much quantity of steel is required for 1m3 concrete

Typically, an average 80 kg to 120 kg of steel quantity are required for 1m3 (cubic meter) of RCC concrete. Normally 1m3 of RCC concrete slab requires an average of 80 kg of steel, a beam requires 120 kg of steel, a column requires 160 kg of steel and a footing requires 40 kg of steel.

The thumb rule for steel in reinforced concrete construction is between 100 and 120 kg/m3 of the calculated wet volume of concrete. For a residential slab it is about 1×7850 × 1% = about 80 kg/m3, for a beam it is 1×7850 × 1.5% = 140 kg/m3, for a column it is 1×7850 × 3% = 160 kg/m3 and for a footing it is 1×7850 × 0.5% = 40 kg/m3.

Now taking various Thumb Rule for Steel quantity calculation for 1 cubic metre concrete.

Thumb Rule for Steel in Kg/m3

1) Thumb rule for steel in rcc slab is 80 kg/cubic meter of wet volume of concrete

2) Thumb rule for steel in beam is 120 kg/cubic meter of wet volume of concrete

3) Thumb rule for steel in column is 160 kg/cubic meter of wet volume of concrete

4) Thumb rule for steel in footing is 40 kg/cubic meter of wet volume of concrete

5) Thumb rule for steel in rcc structure is 100- 120 kg/cubic meter of all calculated wet volume of concrete.

6) Thumb rule for steel in rcc structure is 3.5 Kg to 4 kg/ sq ft of built up area.

Thumb Rule for Steel percentage in concrete formula

1) Thumb rule for Steel in general RCC structure is 1% – 4% of wet volume of concrete

2) Thumb Rule for Steel in column is 2% – 4% of wet volume of concrete

3) Thumb Rule for Steel in beam is 1% – 2% of wet volume of concrete

4) Thumb Rule for Steel in footing is 0.5% – 1% of wet volume of concrete

5) Thumb Rule for Steel in slab is 1% – 1.5% of wet volume of concrete.

How much steel is required for 1m3 concrete slab

Thumb rule for steel in slab = 1% to 1.5%

Typically, an average 80 kg to 120 kg of steel quantity are required for 1m3 (cubic meter) of RCC concrete slab. Normally 1m3 (cubic meter) RCC concrete slab requires an average of 80 kg of steel for a residential building and 120kg of steel for a commercial building.

The minimum quantity of steel required for 1m3 concrete slab is 1%, now 1% of 1m3 = 0.01 m3, and we know that typical weight of 1m3 steel is 7850 kg, so weight of 0.01m3 steel = 0.01 × 7850 = 78.50 kg, so the minimum quantity of steel required for 1m3 concrete slab is 78.50 kg.

The maximum quantity of steel required for 1m3 concrete slab is 1.5%, now 1.5% of 1m3 = 0.015m3, and we know that typical weight of 1m3 steel is 7,850 Kg, so weight of 0.015m3 steel = 0.015 × 7850 = 118 kg, so the maximum quantity of steel required for 1m3 concrete slab is 120 kg.

How much Quantity of steel is required for 1m3 concrete beam

Thumb rule for steel in beam = 1% to 2%

Typically, an average 80 kg to 160 kg of steel quantity are required for 1m3 (cubic meter) of RCC concrete beam. Normally 1m3 (cubic meter) RCC concrete beam requires an average of 80 kg of steel for a residential building and 160kg of steel for a commercial building.

The minimum quantity of steel required for 1m3 concrete beam is 1%, now 1% of 1m3 = 0.01 m3, and we know that typical weight of 1m3 steel is 7850 Kg, so weight of 0.01m3 steel = 0.01 × 7850 = 78.50 kg, so the minimum quantity of steel required for 1m3 concrete beam is 78.50 kg or nearly 80 kg.

The maximum quantity of steel required for 1m3 concrete beam is 2%, now 2% of 1m3 = 0.02m3, and we know that typical weight of 1m3 steel is 7,850 kg, so weight of 0.02m3 steel = 0.02 × 7850 = 157 kg, so the maximum quantity of steel required for 1m3 concrete beam for commercial building is approx 160 kg.

How much quantity of steel is required for 1m3 concrete Column

Thumb rule for steel in slab = 2% to 4%

Typically, an average 160 kg to 320 kg of steel quantity are required for 1m3 (cubic meter) of RCC concrete column. Normally 1m3 (cubic meter) RCC concrete column requires an average of 160 kg of steel for a residential building and 320kg of steel for a commercial building.

The minimum quantity of steel required for 1m3 concrete column is 2%, now 2% of 1m3 = 0.02 m3, and we know that typical weight of 1m3 steel is 7,850 kg, so weight of 0.02m3 steel = 0.02 × 7850 = 157 kg, so the minimum quantity of steel required for 1m3 concrete column for residential building is approx 160 kg.

The maximum quantity of steel required for 1m3 concrete column is 4%, now 4% of 1m3 = 0.04m3, and we know that typical weight of 1m3 steel is 7,850 kg, so weight of 0.04m3 steel = 0.04 × 7850 = 314 kg, so the maximum quantity of steel required for 1m3 concrete column in commercial building is approx 320 Kg.

How much quantity of steel required for 1m3 concrete in footing

Thumb rule for steel in footing = 0.5% to 1%

Typically, an average 40 kg to 80 kg of steel quantity are required for 1m3 (cubic meter) of concrete in footing. Normally 1m3 (cubic meter) RCC concrete footing requires an average of 40 kg of steel for a residential building and 80kg of steel for a commercial building.

The minimum quantity of steel required for 1m3 concrete in footing is 0.5%, now 0.5% of 1m3 = 0.005 m3, and we know that typical weight of 1m3 steel is 7,850 Kg, so weight of 0.005m3 steel = 0.005 × 7850 = 39.25 kg, so the minimum quantity of steel required for 1m3 concrete in footing is approx 40 kg.

The maximum quantity of steel required for 1m3 concrete in footing is 1%, now 1% of 1m3 = 0.01m3, and we know that typical weight of 1m3 steel is 7,850 kg, so weight of 0.01m3 steel = 0.01 × 7850 = 78.50 kg, so the maximum quantity of steel required for 1m3 concrete in footing is 80 kg.
