Description

YL-PL-SR is polycarboxylate ether based high performance copolymer designed for highest concrete quality. It enables concrete to be produced highly workable at low dosage with improved slump retention. Compared to traditional Superplasticizers, YL-PL-SR has higher water reduction, long slump retention, and higher early strength than others.

YL-PL-SR is a neutral concentrate grade, and mainly used as a raw material to produce different types of high performance water reducers for targeted industrial. It complies with ASTM C 494, Type F specifications.

 

Uses

1. YL-PL-SR can be applied in a wide variety industry and can improve the workability to the concrete and to improve high early compressive strength, even with low water/cement ratios while maintaining normal levels of workability. Higher slump retention applications for high strength concrete.

2. It can be widely used in conventional concrete, pumping concrete, super-fluid self-compacting and high-performance concrete; it has the excellent performance especially in the application of high-strength high performance concrete.

 

Advantage

1. Improve slump retention time in concrete.

2. Effect long distance transportation for a long period of time.

3. Reduce slump loss and improve workability.

4. Decrease bleeding of materials separation.

5. High water reducing rate and excellent plasticizing effect. Produces concrete with high levels of workability without segregation.

6. Excellent dispersion and self-compacting effect can produce different grade strength super fluid self-compacting concrete.

7. Can be a substantial increase in early and late strengths of concrete, so that increase the project construction schedule.

8. Better plasticity-maintaining could significantly prolong the transit time of concrete, it reduce economic losses and ensure the normal pumping of concrete.

9. Improves the frost resistance and carbonation resistance of the concrete. Lower drying shrinkage of the concrete by 20% or more compared with naphthalene-based admixtures.

10. High applicability: It can be used with different variety of cement.

11. Improved finished concrete surface ability.

12. Proffer air environment protect.

13. No chloride ions and no corrosion to steel bar.
