What is Self-Consolidating Concrete Mix - CEMEX USA
Self-Consolidating Concrete Mix
Self-Consolidating Concrete (SCC) is a highly fluid mixture designed to flow and consolidate under its own weight. The mixture is very cohesive and is capable of filling all types of spaces without segregation or bleeding.
Product Description
Self-consolidating concrete, also known as self-compacting concrete - a highly flowable, non-segregating concrete that can spread in place, fill formwork and encapsulate the reinforcement without any mechanical consolidation.
Uses/Applications
Commonly used in structural and architectural concrete elements where reinforcing steel is tight and/or surface smoothness is important.
Specifications
ASTM C-94
Product Benefits
- Faster placement
- Improved finish
- Ease of filling restricted sections
- Improved consolidation
- Improved pumpability
- Improved uniformity
- Reduced labor costs
- Quicker concrete discharge
- Elimination of vibrators
- Increased job site safety
SCC is valuable when faced with difficult placement situations and aesthetic challenges. In buildings, structural elements are becoming more and more complex, often requiring highly congested reinforcement. In those situations, conventional methods that are used to consolidate concrete around the reinforcement are impractical, if not, impossible to use. Because of its ability to flow easily and consolidate under its own weight, SCC provides the necessary level of performance without the equipment, manpower and safety concerns of placing conventional concrete.
Another benefit of using SCC would be to enhance a building’s architecture. Today, architects are often asked to create innovative and unique structures. Concrete has always been regarded as the most versatile construction material and SCC has enhanced that position.
SCC mixtures can be designed to mirror virtually any formed surface, from a simple wood texture to intricate carvings. Whatever the owner and architect imagine can likely be produced using self-consolidating concrete.
