Polycarboxylate Superplasticizer Overview
XRT-WC polycarboxylate superplasticizer is made from a modified alkylene polyoxyethylene ether monomer, also called a 6-carbon monomer, producing a 6-carbon polycarboxylate ether superplasticizer. It makes fresh concrete much easier to work with, performing especially well with high-slump, self-leveling, and self-compacting concrete. When using low-quality sand and stone, cement that isn’t well-adapted, or reduced cementitious content, XRT-WC — an eco-friendly polycarboxylate water reducer — greatly stabilizes the slump and improves paste wrapping. It delivers excellent results even where common retarders fail, with clear and reliable performance.
6-carbon PCE Polycarboxylate Superplasticizer Core Features
This is a 6-carbon PCE polycarboxylate superplasticizer, also optimized as a low-slump-loss PCE superplasticizer formulation for long-haul mixes, and is ideal as a polycarboxylate superplasticizer for high-strength precast concrete.
◆High Water Reduction Efficiency
Strong water-reducing power: Boosts concrete fluidity at the same water
content, or cuts mixing water sharply to lift concrete strength while
maintaining consistent flow.
◆Excellent Slump Retention
Minimal long-term slump loss, preserves workability for long-distance transport and high-temp construction, no segregation or
bleeding.
◆ Wide Material Compatibility
Performs well with low-grade sand & stone, high-mud aggregates, ordinary and low-grade cement, and stable even with poorly
adaptable cement.
◆Superior Paste Coating & Workability
Perfect aggregate wrapping, no stratification, enables smooth pumping, ideal for high-slump, self-leveling and self-compacting
concrete.
◆Great for Low-Binder Mixes
Stable work performance in mixes with low cementitious materials, effectively cutting cement costs without compromising quality.
◆ Broad Application Scope
Fixes slump retention and construction issues that regular retarders can’t solve, suitable for both normal and high-temperature
conditions, jobsites.

Recommended Dosage of 6-Carbon Polycarboxylate Superplasticizer (Industry Standard)
Working Condition / Concrete Type
Recommended Dosage (Based on total cementitious materials:
cement + fly ash + mineral powder)
General Recommended Dosage
1.8%～2.5%
Ordinary Pumped Civil Concrete (C30–C40)
1.8%～2.2%
High-Strength Concrete (C50 and above, suitable for C50 C60)
2.2%～2.5%
Manufactured Sand, High Mud Content,
Poor-Quality Aggregate
(good compatibility for poor sand)
2.3%～2.6% (slightly increase)
Low Binder, Cost-Effective Concrete Mix
2.0%～2.4%
Summer High Temperature & Long-Distance Transportation
0.1%～0.2% higher than the general dosage
Winter Low-Temperature Construction
0.1% lower than the general dosage (avoid excessive retarding)
Application Instructions
1. Start trial mixing at 1.8%, then adjust gradually to find the optimal dosage.
2. Low dosage: Poor water reduction, insufficient fluidity, dry mix, and hard to pump.
3. Excessive dosage: Slight retarding, bleeding, and more surface bubbles.

Complete Solutions for High-Temp Projects in South America, Southeast Asia & Africa What role do concrete admixtures play behind common construction headaches in South America, South
Concrete is a fundamental building material in the construction industry. However, its brittleness and susceptibility to cracking have long been challenges for engineers and builders. To address these issues, innovative solutions such as polypropylene (PP) hybrid macro synthetic fibers have emerged
IntroductionWhat is Sodium Gluconate?Sodium gluconate is a white, water-soluble compound made from gluconic acid. Its chemical formula is C₆H₁₁NaO₇. You’ll often find it as a powder or granules. But don’t let that simple appearance fool you—it’s powerful.
Foam formation is a prevalent issue in numerous industrial processes, ranging from wastewater treatment and chemical manufacturing to food and beverage production.
In the realm of modern construction, the search for stronger, more durable materials is ongoing. One such innovation that has dramatically changed the way concrete is used in construction is staple concrete fiber. This specialized material, when mixed into concrete, significantly enhances its strength, performance, and longevity. Whether used in pavements, highways, or structural elements, staple concrete fiber provides numerous advantages that traditional reinforcement methods can’t match.
