Overview of Ultra High Strength CSA Cement (CSA Cement 82.5 92.5)
All raw materials with appropriate ingredients are calcined to obtain hot materials with anhydrous tetracalcium sulfoaluminate and dicalcium silicate as the main minerals, and add appropriate amount of gypsum and activator to grind to produce super high strength. The hydraulic cementing material is called ultra-high-strength CSA Cement, which implements the Q/YTS001-93 standard.
Quality Index of Ultra High Strength CSA Cement (CSA Cement 82.5 92.5)

Features of Ultra High Strength CSA Cement (CSA Cement 82.5 92.5)
1) The Ultra High Strength CSA CEMENT has all the advantages of Rapid hardening CSA cement 42.5.
2) The higher the strength value, the greater the strength increase rate.
3) Acid and alkali corrosion resistance is better than rapid hardening sulfoaluminate cement.
Applications of Ultra High Strength CSA Cement (CSA Cement 82.5 92.5)
Ultra-high-strength CSA cement is used to prepare early-strength, high-strength (concrete above C60), impermeability and sulfate corrosion resistance concrete, negative temperature construction,grout anchoring, support, assembly joints, geological cementing, emergency repairs , Plugging cement products and construction projects.
Storage and Transportation of Ultra High Strength CSA Cement (CSA Cement 82.5 92.5)
Ultra high-strength CSA cement should not be damp and mixed with other types of cement during transportation. It should be stored separately from other types of cement.
The storage period is 6 months in a dry environment. It should be re-inspected after the deadline.
