PCE powder for concrete with 3h+ slump
High-range water-reducing admixture powder
Description
Engineered for the most challenging logistics and environmental conditions, our 3-hour plus slump retention PCE powder utilizes advanced "controlled-release" molecular technology. This ensures that concrete maintains optimal workability from the batching plant to the job site, even under extreme temperatures.
Special Features
Key Technical Advantages:
-Guaranteed 3h+ slump life, eliminating the risk of premature setting during long-distance transit.
-Achieves 25%-35% water reduction while maintaining excellent rheological properties.
-Superior Hot-Weather Performance.
-Significantly improve the surface appearance of concrete.
