CEM II / A-P 52,5 R

Technical Information

This type of cement is designed for demanding construction applications requiring high early and ultimate strength, reliable mechanical performance, and long-term concrete durability. Thanks to the combination of Portland clinker and reactive natural pozzolan, it delivers high performance while reducing environmental impact compared to conventional Portland cements.

Applications

• Ready-mix concrete of higher strength classes
• Precast reinforced concrete elements
• Bridge and civil engineering structures
• Industrial floors
• Cast-in-place load-bearing structures
• Prestressed concrete elements
• Concrete products with short production cycles
• Structures requiring early achievement of design strength

Key Benefits

• Very high early strength enables faster formwork removal and earlier loading of structures.
• High ultimate strength ensures reliability even under demanding structural requirements.
• Excellent workability of concrete mixes while maintaining high strength.
• Higher density of the cement matrix contributes to the long-term durability of concrete structures.
• Improved resistance to aggressive environments due to the pozzolanic reaction.
• Lower carbon footprint compared to CEM I cement of the same strength class.
• Compatible with modern chemical admixtures, including superplasticizers used in high-performance concrete.
