PCE Flake (Polycarboxylate Superplasticizer Flake) is a solid, high-performance water-reducing admixture in flake form, based on advanced polycarboxylate ether technology. It appears as white to off-white solid flakes that are easy to handle, store, and dose, fully soluble in water during concrete mixing. This third-generation superplasticizer achieves exceptional water reduction (up to 25–40%) while providing superior slump retention, making it ideal for high-performance and durable concrete.
Key Features & Advantages
- Ultra-High Water Reduction — 25–40% water reduction for higher strength, lower permeability, and reduced cement usage.
- Excellent Slump Retention — Maintains workability for extended periods (2–4+ hours), perfect for long-distance transport and hot climates.
- High Flowability & Self-Compacting — Enables low water-cement ratio concrete with excellent fluidity and no vibration needed.
- Enhanced Strength Development — Boosts early and ultimate compressive strength significantly.
- Easy Handling & Storage — Solid flake form, no liquid spillage, long shelf life, convenient for dry-mix or remote sites.
- Good Compatibility — Works well with various cements, supplementary materials (fly ash, slag, silica fume), and other admixtures.
- Low Dosage Efficiency — Effective at 0.1–0.5% by cement weight.
- Eco-Friendly — Chloride-free, low alkali, suitable for reinforced concrete and sustainable construction.
Typical Applications
- Ready-mix concrete (pumped, long-haul delivery)
- Precast concrete elements (beams, panels, pipes)
- Self-compacting concrete (SCC) and high-flow mixtures
- High-strength / ultra-high-strength concrete (>C60)
- Mass concrete and large-volume pours
