High Performance Polycarboxylate Super Plasticizer with High Slump Retention And Water Reduction
XRT-SC Polycarboxylate superplasticizer is made of modified alkylene polyoxyethylene ether monomer, also known as six-carbon monomer. Widely used in the synthesis of high water reducing properties of XRT-SC is a new generation of modified polycarboxylic acid superplasticizer polyether independently developed and synthesized, through free radical polymerization with substances containing double bonds (such as acrylic acid, maleic anhydride, etc.) to produce Polycarboxylate superplasticizer.
XRT-SC Polycarboxylate superplasticizer (PCE) is made of modified alkylene polyoxyethylene ether monomer, also known as six-carbon monomer. Widely used in the synthesis of XRT-SC with high water-reducing properties is a new generation of modified polycarboxylic acid superplasticizer polyether, independently developed and synthesized via free-radical polymerization of substances containing double bonds (such as acrylic acid, maleic anhydride, etc.) to produce Polycarboxylate superplasticizer.
The polycarboxylate superplasticizer synthesized from a 6-carbon monomer exhibits good particle dispersion and excellent slump retention, good adaptability and durability, and environmental protection.
Why 6-Carbon PCE Has Excellent Compatibility?
◆ Optimized Molecular Structure
A longer main carbon chain and uniform side chains provide greater steric
hindrance. Stable adsorption on cement particles, avoiding flocculation,
false set, and fast slump loss.
◆ Wide Cement Adaptability
Moderate anion charge fits all common cement types, even low-grade ones
, generic cement. No incompatibility reaction, no sudden slump drop.
◆ High Tolerance to Poor Aggregates
Built-in anti-mud groups resist invalid adsorption from mud and silt. Perfect for manufactured sand, weathered sand, and poorly
graded stone.Stable workability without bleeding, segregation, or sticky base.
◆ Great for Low-Binder Mixes
Slow-release molecular design maintains lasting fluidity and slump retention. Works well in low-cement, low-cost concrete
formulas, with no dry or hard-to-pump mix.
◆ Good Compatibility with Other Admixtures
Stable chemical performance, compatible with retarder, air-entrainer, defoamer, antifreeze, and expansion agent.No flocculation,
no delamination, easy for batching plant compounding.
◆ Wide Temperature Adaptability
Heat and cold resistant structure.Low slump loss in high temperature and long-distance transport; no over-retarding in winter.
◆ Suitable for Special Concrete
Fully fits high-strength, pumped, self-leveling, self-compacting concrete, precast parts, and mortar flooring. No frequent dosage
adjustment needed.

6-Carbon PCE Superplasticizer Performance at Different Temperatures?
◆ Low Temperature 5℃～15℃
This 6-carbon PCE superplasticizer features high initial water reduction and fluidity. It avoids concrete stiffening, over-retarding,
false set, and sticky base. Stable workability keeps steady strength growth even with high-mud aggregates.
◆ Normal Temperature 15℃～28℃
As a low-slump-loss polycarboxylate ether, it delivers balanced water reduction and slump retention. Low time-dependent slump
loss, good wrapping, no segregation or bleeding.Fits ordinary cement and manufactured sand with almost no dosage adjustment.
◆ High Temperature 30℃～40℃
This high-temperature-resistant PCE admixture outperforms 4C/5C PCE in hot weather. It slows cement hydration, prevents early
setting, and surface crusting. Keeps good workability for long transport, no extra retarder needed.
◆ Extreme High Temperature Above 40℃
Maintains stable plasticizing performance far better than ordinary PCE. Only minor dosage tweak needed, effectively solves fast
