Concrete is arguably the most utilized building material with forms of it utilized in construction projects for distinct uses. The two most familiar categories are plain cement concrete (PCC) and reinforced cement concrete (RCC). These findings contribute towards making construction professionals aware of the main differences between PCC and RCC and, therefore, what material to use in a construction project. Explaining the dissimilarities between Public-Private Cooperation (PCC) and Risk Covariance (RCC) is the objective of this blog.
PCC (Plain Cement Concrete)
Plain cement concrete (PCC) is a type of Concrete which does not contain any reinforcement material. It is principally applied where high tensile strength is not required in the structural members or parts in question. PCC bars the concrete structures from coming in direct contact with the sub – soil or water body. It is known for compressive strength and is widely used in structures where tensile strength is not warranted.
Materials used in PCC:
- Coarse aggregate
- Fine aggregate (sand)
- Cement
- Water
The mix ratio of PCC is typically 1:2:4 ( cement:sand ). Its properties include compressive strength, durability and workability. PCC is generally utilised in flooring, pavement, foundation footings and other non-beam and slab elements such as garden paths and boundary walls.
RCC (Reinforced Cement Concrete)
Reinforced cement concrete (RCC) is a concrete to which steel bars are added to increase its load-bearing capacity. This gives it the ability to hold tensile and compressive stress hence making RCC appropriate for members. Some RCCs are used where the load-bearing structures are required and demand high strength with resistance to bending tension members.
Materials used in RCC:
- Sand
- Cement
- Aggregate
- Water
- Steel reinforcement
RCC provides tensile and compressive strength together with a high degree of durability and flexibility. Its reinforcement assists prevent shrinkage and crack.
Difference Between PCC and RCC
| Feature | PCC (Plain Cement Concrete) | RCC (Reinforced Cement Concrete) |
| Composition | Cement, sand, aggregate, and water | Cement, sand, aggregate, water, and steel reinforcement |
| Structural Strength | Designed for compressive strength only | Combines compressive strength of concrete with tensile strength of steel |
| Tensile Strength | Lacks tensile strength; not suitable for tension | Provides tensile strength due to steel reinforcement |
| Load-Bearing Capacity | Suitable for non-load-bearing applications | High load-bearing capacity; ideal for structural components |
| Applications | Pavements, flooring, and non-structural elements | Columns, beams, slabs, and bridges |
| Durability | Durable for non-structural uses; may crack under tension | Highly durable, especially in structural applications |
| Cost | Less expensive; no steel reinforcement | More expensive due to steel and labor |
| Construction Technique | Simple construction process | More complex; involves placing reinforcement and proper curing |
| Maintenance | Low maintenance but may require resurfacing | Requires regular maintenance to prevent corrosion of steel |
| Crack Resistance | Susceptible to cracking and shrinkage | Better crack resistance due to steel |
| Flexibility in Design | Limited flexibility | Allows complex shapes and forms |
| Shock Resistance | Low shock resistance | High shock resistance |
| Yield Strength of Steel | Not applicable | Steel reinforcement typically 200–300 N/mm² |
| Material Use | Suitable for minor construction | Essential for major construction |
| Environmental Resistance | Less resistant to environmental stress | Highly resistant to temperature variation and moisture |
| Vibration Requirement | No vibration required | Requires vibration to ensure proper compaction |
| Curing Process | Standard curing methods | Requires careful curing for strength development |
| Use of Equipment | Does not require specialized equipment | Requires specialized equipment like vibrators |
| Testing | Simple testing of concrete strength | Testing involves both concrete and steel reinforcement |
Considerations in Choosing Between PCC and RCC
Project Requirements
In general, the PCC is used when the project requires a high-quality layer with one or two ‘colors’. PCC is appropriate for elements in which the only force relevant is the vertical compressive load such as pavements and floor slabs in residential buildings. On the other hand RCC is used in load bearing members like columns, beams and slabs carrying the load of the building construction.
Environmental Factors
Location or the prevailing conditions also influence the type of concrete to be used. RCC can be used in regions that experience; temperature fluctuation, high humidity or chemical exposure because RCC has more strength and is less likely to crack as compared to normal concrete. PCC is more vulnerable to changes in the environment but it performs well in laboratory conditions where there are no large changes within temperature or chance upon chemical interaction.
Conclusion
Understanding the distinctions between PCC and RCC is crucial on construction sites. PCC is affordable and suited for non-structural uses, while RCC is ideal for load-bearing applications due to its strength and flexibility. Walls and Dreams emphasizes selecting the right materials based on project needs and environmental factors to ensure safe, stable structures.
FAQs
How good is PCC in withstanding environmental stresses?
That’s right, PCC is less resistant to the environmental stresses as compared to the other Chlorella species.
Does RCC defy environmental conditions?
Yes, RCC is very hard wearing with regard to temperature fluctuations and moisture.
Is vibration necessary while constructing the PCC?
Well, as for the requirement of vibration for PCC construction, it’s also pertinent to answer no.
Does RCC Requires Vibration During Construction?
However, RCC does necessitate vibration so as to achieve maximum compaction.
Is RCC construction complex?
Yes, RCC construction is tougher because of reinforcement storage and placement.
Does PCC require maintenance?
The PCC needs low maintenance but may often have to be resurfaced because of the development of cracks.
