Reinforced Concrete Footing with RCC Concrete Bed

Reinforced concrete footing is a type of foundation that is used to support a building or structure. It is designed to spread the weight of the building over a large area to ensure that the load is distributed evenly. To ensure the strength and durability of the foundation, a concrete bed is provided. In this article, we will discuss the use of RCC concrete bed in reinforced concrete footing.

What is RCC Concrete Bed?

RCC stands for Reinforced Cement Concrete, which is a composite material that is made up of cement, sand, aggregate, and water. The reinforcement is provided in the form of steel bars or mesh, which is embedded in the concrete. RCC concrete bed is a layer of reinforced concrete that is provided at the bottom of the spread footing.

Advantages of RCC Concrete Bed

There are several advantages of providing RCC concrete bed in reinforced concrete footing:

1. Strength: RCC concrete bed provides higher strength to the foundation as compared to lean concrete bed.

2. Durability: RCC concrete bed is more durable and long-lasting than lean concrete bed.

3. Better load distribution: RCC concrete bed ensures better load distribution as compared to lean concrete bed.

4. Prevention of soil erosion: RCC concrete bed prevents soil erosion and provides stability to the foundation.

5. Protection against corrosion: RCC concrete bed protects the reinforcement from corrosion and ensures the longevity of the foundation.

Where is RCC Concrete Bed Provided?

RCC concrete bed can be provided in two ways:

1. At the bottom of spread footing: In this method, RCC concrete bed is provided at the bottom of the spread footing to ensure better load distribution and stability.

2. Instead of lean concrete bed: In this method, RCC concrete bed is provided instead of the lean concrete bed to ensure higher strength and durability of the foundation.

Conclusion

RCC concrete bed is a crucial component of reinforced concrete footing. It provides higher strength, durability, better load distribution, prevention of soil erosion, and protection against corrosion. It can be provided at the bottom of spread footing or instead of the lean concrete bed. The use of RCC concrete bed ensures the longevity and stability of the foundation.
