Advantages of concrete produced with CEM II/B-M (Q-L) 42,5 N 

• Low hydration heat
• High ultimate strength
• Wide range of usage in moderately aggressive environments.
• High workability 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 production of masonry blocks and lightweight concrete.
• Road Pavements Suitable for concrete pavements for roads and wearing surfaces
• General Use All kinds of grout mortar, plaster and repair works.
• Mass concrete.
• All kinds of mortar.

Environment, Safety and Storage 

• Wear suitable protective clothing, gloves,eye and face protection equipment.
• Lower CO2 emission into the atmosphere
• For detailed safety information, please see Technical Data Sheet, available at www.cimpor.com

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.
• Follow the correspondant standard and Specifications for aggressive environments.

Not recommended for:

• Not suitable for ready-mixed concrete productions where early strength is critical.
• Not suitable for concrete production to be poured without any measures under cold weather conditions.
