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 Technical principle:

The product 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:

1. Ultra-High Water Reduction

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

    optimized mix design.

2.Superior Workability

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

   air content for efficient pumping.

3.Exceptional Durability & Strength

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

4.Broad Cement Compatibility

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

5.Eco-Friendly Formulation

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

     manufacturing practices.
