RCC Construction Process | Applications, Pros and Cons

Look around - there's a high chance that almost all the buildings around you have been constructed using RCC. This type of construction has become such an integral part of modern architecture, widely used for its strength, durability, and cost-effectiveness.

Reinforced cement concrete or RCC combines concrete and steel reinforcement to create a robust and durable structure. Reinforcements are embedded within the concrete, allowing the structure to withstand heavy loads, extreme weather conditions, and other stress factors.

RCC Construction Process

  1. Reinforcement Placement
  2. Formwork Preparation
  3. Concrete Pouring and Curing
  4. Finishing and Surface Treatment

1. Reinforcement Placement

Reinforcement placement is a crucial step that involves placing steel reinforcement within the concrete formwork in a specific pattern to provide the necessary strength and durability to the structure. The steel reinforcement, also known as rebar, is embedded within the concrete, allowing the structure to withstand heavy loads, extreme weather conditions, and other stress factors. 

2. Formwork Preparation

Formwork preparation involves creating a mold or formwork that will hold the concrete in place while it sets. The formwork is typically made of wood, steel, or aluminum and is designed to withstand the weight and pressure of the concrete. 

3. Concrete Pouring and Curing

Concrete pouring and curing involve pouring the concrete into the formwork and allowing it to set and cure. The pouring process requires skilled labor and equipment to ensure that the concrete is correctly placed and adequately compacted to eliminate air pockets. The curing process can take several days, depending on the size and complexity of the structure. During the curing process, the concrete gains strength and durability.

4. Finishing and Surface Treatment

Finishing and surface treatment involve applying a variety of finishes and treatments to the concrete surface. This can include the application of coatings, sealants, and other materials to protect the surface from damage and wear. 

Applications of RCC Structures 

1. Residential Buildings

RCC structures are widely used in the construction of residential buildings since they require high structural integrity. Additionally, RCC structures offer superior fire resistance, which is an important factor in residential construction.

Designed by architect Le Corbusier, Villa Savoye is an iconic example of modernist architecture and a key representation of the International Style. Its use of reinforced concrete allowed for a sleek and minimalist design, with the building raised on pilotis or columns, creating an open and functional living space.

2. Commercial Buildings

The cost-effectiveness and strength of RCC structures make them an ideal choice for large-scale commercial projects. These structures can be designed to accommodate long spans and high load-bearing capacities, which makes them ideal for commercial buildings that require large open spaces.

The Shard, located in London, is a 95-story skyscraper that was completed in 2012. The building's unique design required a high degree of structural integrity, which was achieved through the use of RCC structures. The building's shape is inspired by the spires of London churches and the masts of ships that once sailed down the nearby Thames River. The building's RCC core provides its strength and stability. The RCC core is surrounded by steel columns that support the building's weight.

3. Bridges

RCC structures are widely used in the construction of bridges due to their exceptional strength, durability, ability to withstand heavy loads, and extreme weather conditions. Moreover, RCC structures can be designed to accommodate various types of bridges, including arch bridges, cable-stayed bridges, and suspension bridges.

While the bridge's iconic reddish-orange color comes from its steel structure, its towers and many other elements are made of reinforced concrete. The use of RCC in the bridge's construction, particularly in the tower foundations and other structural components, contributed to its durability and strength.

3. Dams

The strength and durability of RCC structures make them an ideal choice for large-scale infrastructure projects like dams. Additionally, they offer superior water-tightness, which is critical for the proper functioning of dams.

The Hoover Dam is a massive RCC structure that was built in the 1930s. The dam's RCC structure was designed to withstand the pressure of the water and prevent the Colorado River from flooding. The dam's concrete was poured in blocks, and each block was allowed to cure before the next one was poured.

Advantages of RCC Structures

1. Durability and Strength

RCC structures have exceptional durability and strength, making them an ideal choice for heavy loads, extreme weather conditions, and other stress factors. The combination of concrete and steel reinforcement helps to create a structure that can withstand significant pressure and flex under stress.

2. Fire Resistance

Fire resistance is an essential consideration in building design, and RCC structures have proven to be highly effective in this area.

3. Cost-Effectiveness

RCC structures are cost-effective compared to other building materials. The use of concrete and steel reinforcement has become so mainstream that procuring materials and labour is relatively inexpensive.

4. Thermal Mass

RCC structures are highly energy-efficient, as concrete has excellent thermal mass properties. This means that it can store and release heat, which helps to regulate the temperature inside the building.

5. Low Maintenance

Buildings constructed using RCC require almost no maintenance, further contributing to their cost-effectiveness over time.

Disadvantages of RCC Construction

1. High Initial Cost

RCC construction can be more expensive upfront due to the cost of materials, formwork, and skilled labor required for proper concrete placement and finishing.

2. Cracking

Concrete is prone to cracking, which can be caused by factors like shrinkage, temperature changes, or settling of the building's foundation. These cracks may need repairs over time.

3. Weight

Concrete is heavy, which can necessitate more robust foundations and structural support. This can be a drawback when building in areas with weak or unstable soil.

4. Environmental Impact

The production of cement, a key component of concrete, generates a significant amount of carbon emissions. This makes concrete construction less environmentally friendly compared to some alternative materials.

5. Limited Flexibility

Once concrete sets, it is challenging to make changes to the structure since modifications can be costly and complex.
