There are various aspects that decide the strength and durability of any construction work; and the choice of materials is one of the significant determinants in this regard. The most frequently used materials in construction works include RCC (Reinforced Cement Concrete) and PCC (Plain Cement Concrete). These two are concrete material; however, they serve two entirely different purposes in the field of construction. It is essential to understand the difference between RCC and PCC.

This piece of writing aims to compare the RCC and PCC in construction, and help you decide which one is better for construction, RCC or PCC.

Understanding PCC (Plain Cement Concrete)

The Plain Cement Concrete can be considered as the simplest form of concrete, which is formed using cement, sand, aggregate, and water in an appropriate ratio. There is no steel or any type of reinforcement present in the PCC.

PCC is generally used when there is a requirement of strength only for compression but not for tension. Since concrete by nature behaves well under compression, it is ideal to use PCC in those places where bending or tensile forces will be negligible. During construction, PCC is often used as a base for construction. PCC helps to create a uniform and clean foundation for further construction work.

The importance of PCC is because of its ability to create uniformity and cleanliness during construction work. When poured on the ground, it acts as a protective layer for steel from corrosion due to the soil. Therefore, PCC is almost always used before the use of RCC in foundation work.

Understanding RCC (Reinforced Cement Concrete)

Reinforced cement concrete (RCC), which can also be called RCC, is a more advanced and strong form of concrete that contains steel reinforcing bars in its make-up. While concrete has great compressive strength, it does not have any tensile strength. On the other hand, steel has very good tensile strength. By combining both, RCC has the capacity to handle both forms of stress.

Such a combination makes RCC vital in modern-day construction. It is used in almost all types of construction components, like beams, columns, slabs, and foundations. Without RCC, it will be impossible to construct tall buildings, bridges, or buildings meant to carry heavy loads.

Moreover, RCC also gives designers great flexibility to use when designing buildings. They can come up with elaborate shapes and large open spaces due to its ability to resist bending forces and cracking.

Difference Between RCC and PCC

This differentiation not only lies in the use of steel, but also refers to their role in construction as well as their reactions under certain situations.

PCC comes under the category of non-structural material and thus is not meant to be able to bear any heavy load. On the other hand, RCC is a structural material which has been developed to bear heavy loads and resist various forces such as bending, tension, and compression.

There is one more major difference that exists in both types of concrete regarding their endurance. While PCC may be enduring enough in case of basic purposes, it still does not possess the strength that RCC possesses as structures built of RCC can last for decades in severe conditions as well.

Finally, there is one more factor which makes RCC and PCC different and that factor is the price. Since PCC does not have steel in it, thus it is relatively cheaper compared to RCC.

Applications of PCC in Construction

PCC finds extensive use wherever strength is not the number one consideration. The first purpose of PCC is that of providing an even surface. Generally, in any construction project, the laying of the concrete happens before starting the construction of foundations. This makes sure that the foundation rests on an even platform free from any soil variations.

Other than foundations, PCC is used in flooring, pavement, and pathways. These materials can be seen in paths, driveways, and small roads where there is no requirement of substantial load-bearing capacity. Simplicity and cost-effectiveness make it a great choice for such purposes.

Applications of RCC in Construction

Usage of RCC is when there is the need for sturdiness and resilience. RCC acts as the skeleton that supports any building and structure. RCC is used in the construction of houses to high-rise buildings.

Beams and columns made of RCC support the entire weight of any building. The floors and roofs of such buildings are made by use of RCC slabs, ensuring uniform distribution of loads on the whole structure. In the case of bridges and dams, RCC is used due to its ability to withstand heavy pressure.

It is possible to use RCC in buildings that are earthquake-resistant because of its flexibility and resistance to damage.

Which is Better: RCC or PCC for Construction?

However, the question of which type is better between RCC and PCC remains unanswered. It depends on the intended use of the structure under consideration.

In case the objective is to build a foundation and a leveled surface, then using PCC becomes an appropriate choice because it is affordable, simple to use, and sufficient for non-structural purposes. On the other hand, when one intends to create a solid structure that should withstand loads and external factors, the usage of RCC becomes inevitable.

As a rule, RCC and PCC are used together in most cases since choosing one or another can cause serious problems.

Role of RCC and PCC in Foundation Work

The foundation is an important part of the construction and plays a critical role in PCC and RCC structures. The construction begins with laying down a PCC floor on the ground. Its purpose is to provide separation between the ground and the structure itself, allowing for an even surface.

Once the floor of PCC is laid down, RCC is used in constructing the foundation of the structure. The reinforced concrete foundation acts to hold the weight of the whole structure and pass that weight to the ground.

In addition to strengthening the foundation, it increases its durability by protecting it from moisture and soil issues.

 Strength and Performance Comparison

Comparing RCC with PCC on the basis of their strength, RCC certainly emerges as the winner. Although PCC can handle compressive forces well, it fails miserably under tensile forces. This makes it unsuitable for construction purposes.

On the other hand, RCC, which includes reinforcement in the form of steel, can handle both kinds of forces efficiently. This makes it ideal for parts of structures that need to bend and stretch, like beams and slabs.

Additionally, RCC exhibits better durability than PCC over time. It resists external factors like temperature changes, moisture, and chemicals far more effectively than PCC.

Cost Consideration in RCC vs PCC

The cost element plays an influential role in construction processes. While PCC is cheaper and uses fewer workers, it is a cost-effective method to be employed. However, it is not a substitute to RCC in areas where strength is a concern.

On the other hand, RCC uses much money initially owing to the steel reinforcement and skillful workers needed. Yet, this is cost-effective in the long run since RCC is more durable.

Deciding which option to adopt by focusing only on the cost aspect is not advisable as this could give rise to erroneous decisions.

Conclusion

Comparison of RCC vs PCC in Construction

In the comparison of RCC vs PCC in Construction, one will observe that both RCC and PCC are equally important; however, both have specific purposes. PCC is the stable base required for construction, whereas RCC is used for constructing the actual structure as the latter provides strength to any building.

Thus, there is no question of asking whether RCC is better than PCC in construction, and vice versa, since a properly constructed building requires both RCC and PCC.

Nowadays, RCC is an essential requirement of construction as it helps build strong buildings. PCC also plays a vital part by providing a proper base and surface on which the building can be erected. for more details you can click here
