------XRT-D
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.
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.
