A recycled material that enhances your mix, Fly Ash is a fine powder that comes from coal combustion, typically resulting from power generation, and one of the most commonly used pozzolans in the construction industry. Pozzolans are siliceous or siliceous/aluminous materials which can form cementitious compounds when mixed with cement and water.
Fly Ash provides a significant contribution to sustainable construction and can contribute to the achievement of LEED (Leadership in Energy and Environmental Design) points. Its use in concrete production consumes less energy and offers improved efficiency and building performance. For each ton of Fly Ash used in place of traditional cement, a reduction of roughly 0.9 tons of carbon dioxide is achieved.
Benefits
In a properly proportioned mix with Portland cement, Fly Ash can improve many of the properties of concrete including:
- Enhanced workability and consolidation
- Increased flexural and compressive strengths
- Improved pumpability
- Reduced drying shrinkage
- Decreased bleeding and segregation
- Diminished permeability
- Better resistance to ASR and sulfate attack
- Lower water requirements
Applications
- Concrete
- Concrete Products Structural fill
- Stabilization of aggregate bases
- Soil stabilization Soil drying
