What is RCC Construction?
RCC (Reinforced Cement Concrete) is a composite material made by combining:
- Cement
- Sand
- Stone aggregates
- Water
- Steel reinforcement (TMT bars)
Concrete provides excellent compressive strength, while steel reinforcement provides tensile strength. Together, they create one of the world’s strongest construction systems.
RCC is commonly used for:
- Individual homes
- Apartments
- Schools
- Hospitals
- Government buildings
- Multi-storey residential projects
What is Steel Structure Construction?
Steel structure construction uses fabricated steel members such as:
