What is RCC Construction and How Does It Work?

Building using RCC Construction means erecting structures made up of Reinforced Cement Concrete. The two materials (concrete and steel) work together as one.

Concrete can withstand compressive loads (loads pressing against each other) but cannot withstand tensile loads. This is where steel comes into play because steel can take tensile loads. These two together form reinforced concrete and this greatly enhances the structure's strength.

In residential constructions, the proportion of this technique makes up almost 70-80% of the entire structure.

How Reinforced Cement Concrete Actually Works in a Structure

For better clarity, let us consider a case study of a slab:

The concrete slab will resist the compressive force resulting from people, furniture, and walls. The steel bars placed within the slab will resist tensile forces that may arise due to bending. As a result, the entire assembly is termed as RCC Structure.

In residential buildings, the compressive strength usually obtained with good design may be in the range of 20 to 40 MPa.

Main Components of RCC

Such a structure must comprise of the following three important ingredients:

• Cement - It acts as the binding agent.
• Fine and coarse aggregate - They give body to the structure.
• Steel bars - They take care of tensile stresses.

In an appropriate proportion when mixed with water, they produce RCC.

Step by Step RCC Construction Process

1. Design and planning - The structural engineer does the load analysis and the placement of steel bars to ensure safety.
2. Placement of reinforcement - Cutting, bending, and placement of bars as per the structural design is done.
3. Formwork / Shuttering - The molds are prepared to keep the concrete intact.
4. Placing of concrete - Placement of fresh concrete in the molds, which is fully covered with steel.
5. Compaction - Use of vibrators to get rid of air pockets and to increase density.
6. Curing - Pouring of water for many days to gain strength.

All these stages together comprise RCC Construction, and even small errors can affect its durability.

Why RCC Is Widely Used in Construction

This system is popular based on its performance :

• A well built reinforced concrete building is able to last for 50 to 100 years.
• It offers excellent protection against earthquakes and wind loads.
• It lowers long term maintenance expenses.
• It facilitates flexibility in design in terms of architecture for residential houses and structures.

Worldwide, more than 70% of modern structures make use of this structural system because of its effectiveness and economy.

Final Thoughts

Modern structures are based on the strength provided by reinforced concrete, and when done right, it guarantees safety and strength as well as longevity of any structure.

At KONNBOT, we understand that construction is more than erecting buildings, but an opportunity to build trust through engineering perfection and proper execution. Any structure that we undertake is meticulously planned and supervised, so that clients can be sure of having a strong and lasting home without any doubts or compromises.
