UHPC grade PCE powder
High-range water-reducing admixture powder
Description
Polycarboxylate superplasticizer powder (PCE Powder for UHPC) is a high-performance admixture specially designed for ultra-high performance concrete (UHPC), featuring deep integration of core technology with application scenarios. UHPC-Grade PCE Powder offers ultra-high water reduction and excellent dispersion stability, effectively reducing mixing resistance at extremely low water-binder ratios while ensuring exceptional fluidity and self-compactability of the slurry, without affecting setting time or early strength development. Its powder form facilitates precise dosing, long-distance transportation, and storage, making it perfectly suited for the automated and large-scale production processes of UHPC precast plants.
