Superplasticizers are powerful chemical admixtures widely used in concrete and cement applications. Our liquid polycarboxylate (PCE) superplasticizer helps reduce water content in concrete while keeping workability stable and slump consistent over time. It works across a variety of cement systems, making it a versatile choice for construction projects.
As a trusted supplier with our own dedicated superplasticizer factory in China, LANDU brings over 17 years of experience in chemical additive formulation. We deliver high-quality products and provide practical technical support, including advice on dosage, slump control, and mix design compatibility—helping your concrete perform exactly as needed.
LANDU Superplasticizer Category:
The latest generation PCE superplasticizer from LANDU ensures maximum water reduction in concrete.
As a trusted superplasticizer supplier, LANDU uses premium raw materials to craft our polycarboxylate ether (PCE) products, delivering key benefits for concrete applications:
Chemical Composition: Water-based solution containing 30–40% active ingredients.
Performance:
Recommended Applications: Ideal for concrete mixing plants and pumped concrete where uniform dispersion and early strength are critical.
Naphthalene-Based High-Efficiency Superplasticizer (SNF)
Naphthalene-based high-efficiency water reducer is synthesized from naphthalene and its derivatives through sulfonation and condensation, with the main component being β-naphthalenesulfonate formaldehyde condensate. It is a non-retarding, non-air-entraining superplasticizer that improves concrete’s impermeability, frost resistance, and durability, while posing no corrosion risk to steel reinforcement.
Applications: Suitable for producing early-strength, high-strength, flowing, and steam-cured concrete, as well as pumpable concrete.
Melamine-Based High-Efficiency Superplasticizer (SM)
Melamine-based high-efficiency superplasticizer is synthesized through controlled condensation of melamine, formaldehyde, and sodium bisulfite.
Dosage: 0.5%–2.0% by weight of cement.
Performance: Provides a water reduction rate of 20%–27% and strength increase of 20%–30%.
Key Features:
Applications: Ideal for early-strength and steam-cured concrete, decorative floors, and white fair-faced concrete panels.
Conventional concrete often faces workability challenges—too much water improves flow but reduces strength, while insufficient water can cause honeycombs and weak spots. Superplasticizers solve this dilemma by dramatically improving flow at lower water-to-cement ratios. The result is concrete that is denser, stronger, more durable, and easier to pump and place—making them indispensable for high-performance construction projects across Europe and beyond.
Superplasticizers are essential for modern concrete construction, improving workability, strength, and durability without increasing water content. At LANDU, our top-selling superplasticizers—Polycarboxylate Ether (PCE), Melamine-based (SMF), and Naphthalene-based (NSF)—deliver reliable performance for a wide range of construction projects across Europe. Whether you need high early strength, enhanced flow, or cost-effective solutions, LANDU has the right additive for your concrete.
As a leading supplier of high-quality superplasticizers, LANDU offers products that enhance every aspect of concrete performance.
Significantly lowers the water-cement ratio, boosting concrete strength by 30%–50% and cutting cement costs by up to 15%.

Powder PCE (98%+ solids) enables high fluidity and low shrinkage for self-levelers, grouts, and repair mortars.
High deformability without segregation, filling complex forms and dense rebar without vibration.
LANDU is committed to consistent quality and dependable supply. We work closely with our partners to provide tailored solutions that fit real project needs. From factory to site, our superplasticizers help you achieve better concrete performance with ease.
In contrast, high-efficiency (naphthalene/melamine-based) and high-performance (polycarboxylate-based) superplasticizers deliver 15–45% water reduction.
Though second-generation types demand higher dosages (0.50–1.0%), they achieve 120–135% strength improvement, while third-generation polycarboxylates, with only 0.20–0.40% dosage, boost strength by 140–200% while drastically reducing shrinkage (28-day shrinkage ratio 95–110%).
They also maintain excellent slump retention and compatibility with diverse cementitious systems, supporting modern high-performance concrete production.
For LANDU, this means tailored solutions: ordinary reducers serve basic needs, while advanced superplasticizers meet today’s stringent construction demands for strength, durability, and workability.
LANDU PCE is a high-performance water reducer designed to boost concrete workability, reduce water demand, and enhance strength for high-strength, self-compacting, and durable structures.
LANDU PCE delivers higher water reduction (25–45%), lower dosage (0.2–0.4%), and better slump retention than older generations, making it ideal for modern high-performance concrete applications.
The typical dosage of LANDU PCE ranges from 0.2% to 0.4% by weight of cementitious materials, adjusted based on mix design and project requirements.
Yes, LANDU – Superplasticizer Supplier can significantly improve concrete strength, with 28-day compressive strength ratios reaching 140–200% compared to plain concrete.
LANDU’s superplasticizer powder is compatible with most common admixtures, including air-entraining agents and retarders, though compatibility testing is recommended for specific mixes.
LANDU offers both powder and liquid PCE. Powder can be directly mixed with dry materials, while liquid is added during mixing for precise dosage control.
Overdosing LANDU PCE can cause excessive slump, segregation, and delayed setting.
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.
