Summary
- PCC has no steel reinforcement and is generally used for base, flooring, levelling, and other non-structural construction applications.
- RCC combines concrete with steel reinforcement and is commonly used for structural elements such as beams, columns, slabs, and footings.
- Your choice between PCC and RCC should depend on project requirements, structural design, intended application, and applicable construction standards.
PCC and RCC differ mainly in reinforcement and structural function. Plain Cement Concrete does not contain steel reinforcement. Reinforced Cement Concrete adds steel bars or mesh to improve its tensile and flexural performance. Both are widely used in construction but have different applications.
In this blog, we will compare PCC vs RCC and help you choose the right concrete for your project.
What is PPC and Where Is It Used?
PCC stands for Plain Cement Concrete. PCC is concrete made from cement, water, fine aggregate, and coarse aggregate. It does not contain steel reinforcement. It's built for compressive strength rather than tensile strength.
PCC is commonly used where concrete does not need reinforcement. Typical PCC applications include:
- Levelling and base layers
- Flooring and paving bases
- Filling and other non-structural applications
- Bedding below structural elements
PCC offers a stable and durable base to build on. However, it does not have steel reinforcement to resist tensile stresses. The exact mix and application should follow the project's specifications and applicable standards.

What is RCC and Why Is Reinforcement Used?
RCC stands for Reinforced Cement Concrete. The base remains the same: cement, water, fine aggregate, and coarse aggregate. RCC combines concrete with steel reinforcement. Steel bars or mesh are embedded inside to handle structural stresses.
Steel reinforcement helps the composite member resist tensile and flexural stresses. RCC is used for structural elements such as:
- Beams
- Columns
- Slabs
- Structural Walls
- Reinforced Footings
IS 456:2000 covers the general structural use of plain and reinforced concrete. Steel reinforcement used in concrete is covered by standards such as IS 1786. The standard specifies requirements for high-strength deformed steel bars and wires.

Comparing PCC and RCC: Key Differences
The main difference between PCC and RCC is the presence of reinforcement and the resulting structural application.
| Factor | PCC | RCC |
|---|---|---|
| Reinforcement | No Reinforcement | Steel reinforcement for structural strength |
| Main function | Base and non-structural work | Structural load-bearing applications |
| Tensile resistance | Limited | Improved through reinforcement |
| Common applications | Levelling, bedding, flooring base | Beams, slabs, columns |
| Cost | Generally lower | Higher because of reinforcement |
| Design | Depends on application | Requires structural design |
Choosing Between PCC and RCC for Your Project
PCC is more suitable for non-structural applications like flooring and levelling. RCC is used for structural applications that require reinforcement.
| Project Requirement | Typical Choice |
|---|---|
| Providing a level or stable base below structural work | PCC |
| Flooring or other non-structural applications | PCC |
| Structural slabs | RCC |
| Beams and columns | RCC |
| Reinforced footings and other structural elements | RCC |
The final choice should follow the structural design and project specifications. PCC can also serve as a base or blinding layer below a reinforced footing. The two materials can therefore be used together rather than treated as competing alternatives.
Long-term Performance and Maintenance of PCC vs RCC
Both PCC and RCC can provide durable construction when they are properly placed and cured. However, RCC will require additional care as its steel reinforcements should be protected from corrosion.
- Durability
PCC does not have steel reinforcements, so it will not have corrosion concerns. The durability of the PCC will depend on the quality of the material used and proper construction.
RCC combines concrete with steel reinforcements. Proper concrete cover and good quality of concrete can protect the steel reinforcement from corrosion.
- Maintenance Requirements
PCC has simpler maintenance requirements. The maintenance depends on application and exposure conditions. Cracks and surface damage should be inspected and repaired as they appear. RCC will require maintenance of concrete and reinforcement. Exposed reinforcement or any surface damage on concrete should be addressed promptly. This will prevent water from entering the concrete and triggering corrosion.

PCC vs RCC: What is the Cost Difference?
PCC is less expensive than RCC as it does not require steel reinforcements and the labour cost involved with it. The total cost of each type of concrete will depend on:
- Concrete grade
- Material quality
- Labour rates
- Project size
- Site conditions
PCC can be a cost-effective choice for applications where structural reinforcement is not required. RCC may have a higher initial cost. This is why RCC is used where the project design requires reinforced concrete to handle structural loads.
RCC will cost more than PCC as it will include:
- Steel reinforcements
- Cutting, bending, placing, and tying of reinforcement
- Structural design and formwork
- Additional labour for reinforcement
- Detailed curing
Frequently Asked Questions
What is the main difference between PCC and RCC?
PCC does not contain steel reinforcement. RCC includes steel bars or mesh to improve the tensile strength of the structure. PCC is used in non-structural applications like flooring and levelling. RCC is used only for structural applications like beams and columns.
What is PCC full form in civil engineering?
PCC stands for Plain Cement Concrete. It is a type of concrete made using cement, aggregates, and water without steel reinforcement. PCC is commonly used for base layers, foundation beds, flooring, and other non-structural applications.
Is PCC or RCC more expensive?
RCC is often more expensive than PCC. Reinforcement steel, fixing, formwork, labour, and structural detailing can increase the total cost.
Why is PCC used for non-structural applications?
PCC is used for non-structural applications because these applications do not require reinforcement. PCC can provide a stable and firm base for construction.
Can PCC replace RCC in a structural element?
PCC should not replace RCC where structural design requires reinforced concrete. The concrete type should follow the structural drawings and applicable standards.
