Related admixture:XRT-C is compatible with high-range water-reducing PCE superplasticizers, XRT-DS, and sodium gluconate. For specific dosage recommendations, please contact us.
About High slump concrete, self-leveling concrete, self-sealing concrete,our XRT-DS is best.
XRT-DS Polycarboxylate Superplasticizer offers excellent slump retention, though it does not reduce water. It is ideal for concrete with poor aggregate quality, low cement compatibility, or low cementitious content, significantly improving workability, cohesion, and anti-bleeding properties—especially where standard retarders fail. Suitable for high-slump, self-leveling, and self-compacting concrete.
Related chemical additives:When combined with high-range water reducers, XRT-DS can lower their dosage, reducing cost. With high XRT-DS dosage, adding retarders like sodium gluconate or sugar allows reducing XRT-DS use. Below 5°C ambient temperature, combine with an accelerator.
Pumped, superfluid self-compacting, high-performance, and ready-mixed concrete.
XRT-E Polycarboxylate Superplasticizer delivers excellent performance with high water reduction and minimal slump loss. It enhances concrete workability, providing a cohesive, non-segregating mix that is ideal for pumping. This admixture improves both strength and durability, making it suitable for pumped, superfluid self-compacting, high-performance, and ready-mixed concrete. For precast components, XRT-E promotes early and high strength, accelerates mold turnover, and improves surface finish.
For ready-mixed pumped concrete, high-grade ready-mixed concrete, mass concrete, and highly fluid self-compacting concrete with dense reinforcement or complex vibration requirements.
Compared to conventional water reducers, XRT-FL offers high water reduction, low dosage, minimal slump loss, and is non-toxic and eco-friendly. It enables the production of high-performance concrete with low cement content, excellent workability, and enhanced durability.
Related admixture:Available in flake form, XRT-FL dissolves directly in water. With added retarders, it requires only accurate dosing and thorough mixing. Contact us for more information!
Which type of synthetic fiber is used in railway bridges?
Which type of synthetic fiber is used in the pressure-bearing parts of concrete engineering structures，such as factory floor,highways ,railway bridges?

Why are polycarboxylate superplasticizers needed? — Limitations of traditional superplasticizers
A Polycarboxylate superplasticizers (PCEs) overcome key limitations of traditional superplasticizers. Older types rely on electrostatic repulsion, which fades quickly and causes rapid slump loss. PCEs use a "comb-shaped" polymer structure that provides strong steric hindrance. This creates a physical barrier between cement particles, resulting in superior, longer-lasting dispersion. This mechanism enables critical benefits: prolonged workability for modern construction needs and high water reduction for stronger, more durable concrete. PCEs are therefore essential for advanced concrete technology.
Synthetic fibers are added to concrete to counteract its inherent flaws: low tensile strength and brittleness. These properties cause concrete to crack easily under stress and shrinkage. The randomly distributed fibers create a microscopic network that performs two key functions: Controls Cracking: They bridge across micro-cracks that form during plastic shrinkage and under load, preventing them from widening. Increases Toughness: They hold the matrix together after cracking, forcing fibers to pull out instead of allowing brittle failure. This greatly improves impact and shock resistance. Primarily, synthetic fibers enhance concrete's toughness and control plastic shrinkage, complementing the primary tensile strength provided by steel rebar to create a superior, more durable composite material.
