Self compacted concrete
Self-Compacted Concrete (SCC), also known as Self-Consolidating Concrete, is a highly flowable, non-segregating concrete that spreads into place and fills formwork without the need for mechanical vibration. It is designed to achieve excellent filling ability, high passing ability through reinforcements, and resistance to segregation.
Key Characteristics:
1. High Workability: SCC flows easily under its own weight, making it suitable for complex and densely reinforced structures.
2. No Vibration Required: Eliminates the need for external or internal vibration during placement.
3. Homogeneous Composition: Resists segregation and maintains a uniform mix throughout.
Advantages:
Improved Construction Speed: Reduces labor and time by eliminating vibration.
Better Surface Finish: Produces smoother and defect-free surfaces.
Reduced Noise Pollution: Minimizes the noise from vibration equipment.
Enhanced Durability: Ensures better compaction, reducing voids and increasing the lifespan of the structure.
Ease of Use in Complex Structures: Easily flows around reinforcements and fills intricate molds or formwork.
Applications:
Heavily reinforced structures such as beams, columns, and walls.
Precast concrete manufacturing.
Repair and rehabilitation of structures.
Architectural concrete requiring superior surface finishes.
Typical Mix Design Components:
1. Cement: Acts as a binder.
2. Fine Aggregates: Sand or similar materials.
3. Coarse Aggregates: Typically smaller in size to ensure flowability.
4. Water: For hydration and workability.
5. Superplasticizers: To improve fluidity without adding excessive water.
6. Viscosity Modifying Agents (VMA): To prevent segregation and maintain uniformity.
SCC has become increasingly popular due to its efficiency and ability to produce high-quality structures with minimal manual effort.
