PPC Fly Ash – Sustainable, High-Quality Cement Extender
Improve your concrete, bricks, soil stabilization, and environmental footprint with PPC Fly Ash, now available from SA Home Builder Store. Derived from power station combustion residue, this finely processed ash offers a cost-effective and eco-friendly alternative to traditional cement components.

Product Types: Classified vs. Unclassified
- Unclassified Fly Ash (Class N / UCFA): Coarser, granular fly ash—excellent when slow pozzolanic action is needed in concrete or cementitious mixes.
- Classified Fly Ash (Class S / CFA): Finer, sifted fly ash—ideal when faster reaction and improved strength gain are required.

Key Benefits of Using PPC Fly Ash
- Cement Extension & Clinker Reduction: Lowers cement demand and decreases CO₂ emissions.
- Enhanced Concrete Strength & Durability: Improves long-term strength and resistance to sulfate and chloride attack.
- Lower Heat of Hydration: Ideal for mass pours where temperature control is critical.
- Improved Workability: Spherical particles reduce water demand and increase plasticity.
- Pore Refinement & Reduced Permeability: Enhances concrete density and durability.
- Versatile Applications: From brick/block manufacturing to soil stabilization and mining rehabilitation.
Technical & Environmental Advantages
South African fly ash is pozzolanic, cement-enhancing material composed of alumina-silicates and calcium compounds. It helps reduce waste from coal power stations and supports circular economy principles. Utilizing fly ash aligns with global sustainability goals—reducing landfill use, cutting carbon emissions, and conserving natural resources.
Where It’s Made & Available
