How much steel is in RCC?

As a planning figure, slabs use about 80 kg of steel per cubic metre of concrete, beams 100 to 120, columns 130 to 160 and footings 50 to 70. The exact amount comes from the structural design and bar-bending schedule.

Reinforced cement concrete is concrete with steel bars embedded to carry tension. It is used for slabs, beams, columns and footings that bear load.

How is RCC concrete quantity calculated?

Multiply the member dimensions for the volume, scale by 1.54 for dry volume, then split by the grade ratio for cement, sand and aggregate. Steel is estimated from a kg-per-cubic-metre figure for the member.

RCC Calculator

Estimate concrete and reinforcement for an RCC member — slab, beam, column or footing. Enter the dimensions and grade; steel defaults to a typical kg-per-m³ figure for that member, which you can override.

How it's calculated

Concrete volume is length × width × depth, scaled by 1.54 to dry volume and split by the grade ratio. Reinforcement is the volume × your kg-per-m³ figure — preset to a typical value for the member you choose, but always confirm against the structural drawing.

Steel is a planning estimate, not a bar-bending schedule. The real quantity depends on bar sizes, spacing, laps and hooks in the design.

Frequently asked questions

Steel per m³ by member?

Roughly slab 80, beam 100–120, column 130–160, footing 50–70 kg/m³.

Is this the design quantity?

No — it's a planning figure. The exact steel comes from the structural design and BBS.

Which grade for RCC?

M20 is common for residential RCC; follow the design for higher grades.
