Water Reducing Polycarboxylate Superplasticizer is a high-range water-reducing admixture for concrete. Unlike traditional naphthalene-based or melamine-based superplasticizers, PCE achieves ≥40% water reduction at a lower dosage of 0.2%-0.5% while maintaining slump retention for over 2 hours. It is widely used in ready-mix concrete, precast elements, and high-performance infrastructure projects where workability and strength are critical.

A： Standard MOQ is 20 tons for liquid PCE (one flexitank) and 15 tons for powder PCE. Sample orders of 1kg (powder) or 5kg (liquid) are available for lab testing. For large-scale projects, we can negotiate flexible MOQ based on your timeline.
Yes. Free 1kg powder sample is available for qualified customers. Liquid sample (5kg) is also available upon request.
A： Sample orders: 3-5 business days. Bulk orders (20-100 tons): 15-20 days after deposit confirmation. Large orders (>100 tons): 25-30 days, subject to production schedule. We will confirm exact lead time upon order confirmation.
A： Yes. We offer customized PCE formulation including:
Solid content: 20%-50% for liquid / 98%+ for powder
Functional types: early-strength, slump-retaining, retarding, anti-clay
Tailored to your local cement type, aggregate clay content, and climate
Minimum 5 tons for custom formulation orders
A： Store liquid PCE in 5°C – 40°C environment, in sealed plastic containers or IBC tanks. Avoid iron/steel containers as PCE is mildly acidic. If frozen, thaw naturally and stir thoroughly before use — performance can be fully restored. Shelf life: 6-18 months depending on formulation.

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.
