RCC Full Form (Reinforced Cement Concrete)
CivilSite.in — tools for Indian construction
Updated
RCC stands for Reinforced Cement Concrete — concrete with steel reinforcement bars embedded in it. The concrete carries compression, the steel carries tension, and together they make the beams, columns and slabs that hold a modern building up.
Why steel is added to concrete
Concrete is strong in compression but roughly ten times weaker in tension — it cracks and fails when stretched. Steel is excellent in tension. By casting steel bars where a member is being stretched (the bottom of a simply supported beam, the top of a cantilever), the two materials act together: this is the whole idea of "reinforced" concrete. They also expand and contract at nearly the same rate with temperature, so they stay bonded.
Where RCC is used in a house
- Foundations (footings, rafts)
- Columns — the vertical load-carrying members
- Beams — spanning between columns
- Slabs — the floors and roof
- Staircases, lintels, chhajjas and water tanks
RCC design in India follows IS 456:2000, which fixes the grade, cover, mix and reinforcement rules.
RCC vs PCC
| RCC | PCC | |
|---|---|---|
| Steel | Yes | No |
| Carries | Compression and tension | Compression only |
| Used for | Beams, columns, slabs, footings | Levelling course, blinding under footings |
PCC (Plain Cement Concrete) has no steel and is used as a base layer, not as a load-carrying member.
Frequently asked questions
What is the full form of RCC? Reinforced Cement Concrete — concrete strengthened with steel reinforcement bars.
Why is steel used in RCC? Concrete is weak in tension; steel carries the tension while concrete carries the compression, so the two work together in beams, slabs and columns.
What is the difference between RCC and PCC? RCC contains steel reinforcement and carries both compression and tension; PCC (plain cement concrete) has no steel and is used only as a levelling or base course.
Which IS code is used for RCC? IS 456:2000, the Indian code of practice for plain and reinforced concrete.
