PCE-based concrete water reducer for ultra-high performance applications

What is Polycarboxylate Superplasticizer (PCE)?

Polycarboxylate superplasticizer (PCE) is a third-generation concrete water reducer, engineered using advanced copolymer technology. Its molecular structure consists of a comb-like chain with a polycarboxylate backbone and polyether side chains, which provides excellent dispersion, superior water reduction, and outstanding slump retention.

ISO 9001:2015 ASTM C494 GB 8076-2008

Enables reduction of water by up to 40% while ensuring workability
Lowers cement dosage, reducing CO₂ footprint
Excellent adaptability in precast, pumped, self-compacting concrete

Polycarboxylate ether (PCE) synthesis reaction apparatus – core to next-gen water reducers

Manufacturing Process: Concrete Water Reducer (PCE)

1. Raw Material Preparation: Selection and weighing of acrylic acid, polyether macromonomer, and initiator chemicals. ISO 22196

↓

2. Mixing & Polymerization: Monomers are blended in a reactor, initiated at controlled temperature (70–90°C), under nitrogen protection to avoid side-reactions.

↓

3. Neutralization & Adjustment: Product pH is tuned, impurities removed, and targeted molecular weight achieved (via CNC process controls).

↓

4. Quality Inspection: Viscosity, water reduction rate, chloride content, and residue are tested. ASTM C494

↓

5. Storage & Packaging: The final concrete water reducer is transferred to ISO-grade tanks, ensuring 12–24 month shelf life under standard conditions.

Manufacturing highlights: PCE is synthesized via free-radical polymerization, leveraging both alkali and thermal equilibration. Automated dosing and closed-loop CNC controls ensure batch-to-batch consistency. Each batch undergoes rigorous material traceability and quality checks (ISO-certified).
