 Key Features

1. Excellent slump retention: Slump loss less than 20mm within 2 hours, effectively solves concrete slump loss problem under high temperature and long-distance transportation

2. High water reduction rate: Water reduction rate ≥25%, meets concrete strength development requirements while ensuring slump retention performance

3. Excellent workability: Good concrete cohesion, no bleeding or segregation, excellent pumpability

4. Strong adaptability: Good compatibility with different types of cement, admixtures and other additives

5. Adjustable setting time: Setting time can be adjusted according to construction requirements without affecting later concrete strength

6. Green environmental protection: Non-toxic, non-irritating, chloride-free, no corrosion to steel bars
