Advantages of concrete produced with CEM I 42.5 R

• High early strength
• High ultimate strength
• Particularly suitable for XC exposure classes.

Recommended Applications

• Ready – Mix Concrete Suitable for the production of all comprehensive strength classes. It gives high performance especially in C20/25 to C40/50.
• Precast Production Suitable for the production of precast and prestressed concrete.
• Road Pavements Suitable for concrete pavements for roads with heavy traffic.
• General Use All kinds of grout mortar, plaster and repair works.

Environment, Safety and Storage

• Wear suitable protective clothing, gloves,eye and face protection equipment In case the bagged cement contains chromium (VI), the shelf life is two months after the date of bagging, provided that the storage conditions indicated on the packaging are met. In case the bagged cement contains chromium (VI), shelf life is two months after the bagging date if storage conditions are respected.
• For detailed safety information, please contact with our Sales Department.

Precautions in Application

• Follow the standard minimum cement content and maximum water/cement ratio. 
• Provide adequate protection and cure according to correspondent standards.
• Keep framework and scaffolding in place until adequate mechanical strength is obtained.
• Ready-mix concrete: avoid long time transportation.Pour the concrete in hot and dry environment.

Not recommended for:

• Aggressive environments - water and soil.
• Mass concrete.
• Mortars for general use.
