This liquid polycarboxylate (PCE) superplasticizer is used to reduce water content in concrete while maintaining workability and consistent slump over time. It is suitable for a range of cement systems, though performance may vary depending on materials and mix design.
LANDU is a premier Chinese manufacturer of PCE liquid (Polycarboxylate Superplasticizer). Our liquid PCE acts as a advanced cement dispersant for modern concrete systems, delivering 30–40% water reduction, ≥2h slump retention, and early & final strength improvement. Used in highways, bridges, high-rise buildings, and precast concrete, LANDU provides a trusted, cost-effective alternative to European and Japanese PCE suppliers—fully compliant with ASTM C494 and BS EN 934.

A: PCE liquid (Polycarboxylate Ether) is a high-performance concrete admixture that dramatically reduces water content while maintaining excellent workability. It is the most efficient cement dispersant widely used in modern concrete production.
A: PCE stands for Polycarboxylate Ether. It is the key polymer component in advanced high-range water reducers and the most widely adopted superplasticizer in modern construction.
A: PCE liquid is used to produce stronger, more flowable concrete with lower water-cement ratios. Common applications include ready-mix concrete, precast components, high-rise buildings, bridges, dams and tunnels.
A: Polycarboxylate ether (PCE) is the active polymer in high-performance superplasticizers. It disperses cement particles efficiently, allowing concrete to flow easily without extra water, resulting in higher strength and better long-term durability.
A: PCE delivers 30–40% water reduction, compared to 15–25% for SNF. PCE also provides better slump retention and wider compatibility with different cements. SNF is a more traditional, lower-cost option but with weaker overall performance.
A: PCE liquid is generally priced from $X to $Y per ton for 40%–50% concentration, depending on order volume, specifications and destination. For an accurate quote, please share your dosage requirement and delivery location.
A: As a professional PCE manufacturer, LANDU offers competitive and stable pricing based on solid content, performance grade and order quantity. Contact us directly for the latest factory quotation.
A: Not in real application. While PCE may cost more per ton than traditional admixtures, it reduces total project cost by lowering cement consumption, improving pumping efficiency and reducing construction failures.
A: PCE liquid is ready to use and ideal for ready-mix batching plants. PCE powder is highly concentrated, more cost-effective for long-distance shipping, and suitable for dry-mix products and remote construction sites.
A: A standard PCE formulation consists of 20–50% PCE polymer, water, and small amounts of stabilizers, retarders or slump retention additives. The exact composition varies by grade, such as high water reduction or long slump retention types.
LANDU PCE has been a game-changer for our ready-mix operations during the harsh winters in Bavaria. The slump retention is remarkably stable, maintaining flowability for over 90 minutes without overdosing. Polycarboxylate Superplasticizer (PCE) also meets our local water protection class (AwSV) standards, which is a relief for our compliance team.
Munich, Germany
We switched to LANDU Polycarboxylate Superplasticizer (PCE) for our precast concrete line in Warsaw. The early strength gain is impressive—we consistently achieve 70% of design strength within 18 hours, allowing for overnight demolding. This has increased our production throughput by 20% without adding more beds.
Mexico City, Mexico
For our infrastructure project in Rotterdam, we needed a superplasticizer that performs reliably in highly congested reinforcement zones. LANDU provided excellent viscosity without segregation, and the final chloride content was well below 0.1%. This is a solid choice for European standards.
