Special properties of concrete manufactured with this cement

• Concrete requiring lower heat of hydration.
• Slow strength development at an early age.
• High workability.
• Particularly suitable for XC Exposure Classes.

Recommended uses

• Reinforced concrete suitable for all classes from C12/15 to C25/30.
• Prefabrication of masonry blocks and dome in lightweight concrete Artefacts.
• Road pavements.
• Base and sub-base layers in poor concrete.
• Simple concrete for general use for foundations and elevations.
• Mass concrete.

Environment and Safety

• Wear suitable protective clothing, gloves, and eye/face protection.
• The production of this cement accounts for a decrease in CO2 emissions into the atmosphere.
• For more information, consult the Safety Data Sheet, available at www.cimpor-portugal.pt  

Precautions in application

• Respect the minimum cement dosages and the maximum normative water/cement ratios.
• Ensure an adequate cure and protection according to normative provisions.
• Do not remove formwork or shoring before the concrete sufficiently solid.
• For aggressive environments, follow the normative recommendations and technical texts on the subject strictly.

Contraindications

• Concrete requiring quick strength.
• Concrete under low temperatures.
