Polycarboxylate Superplasticizer

Polycarboxylate Superplasticizer Product Overview

XRT-D polycarboxylate superplasticizer is a next-generation polycarboxylic acid superplasticizer synthesized via free radical polymerization of polyoxyethylene ether macromonomer, unsaturated carboxylic acid, and sulfonic acid monomers. It offers exceptional water-reducing efficiency and low slump loss, ensuring high-performance concrete mix design.

With a high water reduction rate, it enables significant water reduction critical for strength and durability. Its low slump loss maintains workability, reducing on-site adjustments and improving efficiency.

Suitable for pumped concrete, self-compacting concrete, high-strength/high-performance concrete, and commercial concrete, XRT-D adapts to diverse applications, delivering reliable performance and mix optimization.


Polycarboxylate Superplasticizer

Polycarboxylate Superplasticizer Technical principle

XRT-D polycarboxylate superplasticizer has a comb structure, the molecule has a longer length is polyoxyethylene long chain and high density sulfonic acid group, so that it has a greater steric hindrance and electrostatic repulsion effect, providing greater dispersion and higher water reduction rate for cement.

Key Features of Polycarboxylate Superplasticizer

◆ Ultra-High Water Reduction

      Delivers excellent dispersion and a water reduction rate exceeding 40%, ensuring high-grade concrete production 

       with optimized mix design.

◆ Superior Workability

      Provides high fluidity for easy pouring and dense compaction, reducing concrete viscosity while maintaining ideal 

      cohesion and air content for efficient pumping.

◆Exceptional Durability & Strength

     Ensures high strength at all ages, stable volume, and strong resistance to permeability, freeze-thaw, corrosion, and 

      carbonation.

◆ Broad Cement Compatibility

      Adapts well to Portland, ordinary Portland, slag, fly ash, and pozzolanic cements, as well as various admixtures.

◆ Eco-Friendly Formulation

      Uses non-toxic, sustainable raw materials with zero waste discharge during production, aligning with green    

          manufacturing practices.
