Polycarboxylate Water Reducer Superplasticizer with 30-40% Water Reduction for Concrete Mixing

Product Specifications

Overcoming Concrete Mix Challenges with Polycarboxylate Superplasticizer HLP-ME250

Concrete producers and construction engineers often face critical issues like inconsistent water reduction rates causing mix instability, high chloride content leading to rebar corrosion, and supply chain delays disrupting project timelines. In our 10+ years serving global construction projects, we’ve witnessed how substandard water reducers can compromise concrete strength by 15-20% or trigger costly rework due to unexpected slump loss.

A Stable Solution for High-Performance Concrete Mixes

Our Polycarboxylate Superplasticizer addresses these challenges through precise formulation control. With a guaranteed 30-40% water reduction rate and chloride ion content ≤0.2%, it ensures consistent concrete workability while minimizing corrosion risks. As a trusted supplier to 10000+ industrial clients across 50+ countries, we maintain production capacity to fulfill bulk orders within 72 hours, eliminating project delays caused by material shortages.

Key Applications in Modern Construction

This High-range Water-reducing Agent is indispensable for producing high-performance concrete in infrastructure projects, precast elements, and high-rise construction. Its ability to reduce water content while maintaining flowability makes it ideal for self-compacting concrete, shotcrete, and concrete requiring extended workability. It’s widely used in bridge construction, tunnel lining, and architectural concrete where strength, durability, and finish quality are critical.

Critical Specifications for Reliable Concrete Performance

The 50±2% total content ensures optimal dispersing efficiency—too low and water reduction suffers, too high risks segregation. The 1.10±0.02 g/cm³ density guarantees batch-to-batch consistency, preventing unexpected slump variations during mixing. pH value 5.5±1.5 minimizes alkaline aggregate reaction, while total alkali ≤10.0% complies with strict durability standards for marine and coastal structures. These specifications directly translate to concrete with 28-day compressive strength improvements of 20-30% compared to conventional mixes.

Long-Term Value Through Quality and Consistency

Using our Polycarboxylate Water Reducer reduces cement consumption by 8-12% while enhancing concrete durability, delivering lifetime cost savings that far exceed material expenses. In contrast, inferior products often lead to increased water usage, higher cement costs, and premature concrete deterioration. Our production adheres to ISO 9001 standards, with each batch undergoing rigorous testing to ensure compliance with ASTM C494 and EN 934-2 specifications, providing long-term supply stability for large-scale projects.

Our Commitment to Quality Assurance

Certificate of Analysis & Documentation

Each delivery includes a batch-specific COA with test results for all key parameters, along with a detailed MSDS compliant with GHS standards. For critical projects, we can provide additional third-party testing reports from SGS or Intertek upon request. Historical batch data is retained for 5 years, allowing traceability for long-term infrastructure projects.

Storage & Handling

• Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
• Keep away from incompatible materials, food and feed sources.
• Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
• Follow good industrial hygiene practices. Avoid inhalation and skin contact.
• Refer to MSDS for detailed storage and safety instructions.
