Composite Portland Cement
Main Information
Description
Composite Portland cement is a type of hydraulic cement that becomes strong and solid through hydration reactions when combined with water. This cement is produced from a combination of hydraulic lime and clay, playing a very important role in the construction industry.
Product Technical Description
Precautions for Using Composite Portland Cement
In cold weather conditions and environments where there is a risk of freezing, the use of this type of cement must be done carefully and following specific requirements. Pouring concrete in these conditions requires temperature and timing control to prevent structural damage.
For jobs such as building construction or tile installation, especially when done after the main concrete has been placed, this type of cement is considered a secondary option after Type 1 or Type 2 cement.
Composite Portland Cement
Composite Portland cement, thanks to the combination of active mineral materials with base cement, offers better performance in the production of advanced concretes. Its most prominent features are listed below:
- Improved properties: This cement reduces permeability and prevents water and moisture from entering the concrete.
- Enhanced workability during application: The compounds in this cement make concrete pouring easier and improve the quality of the finished structure.
- Higher final strength: Over time, concrete produced with this cement achieves greater compressive and flexural strength than regular concrete.
- Better pumping and flow: Suitable for projects that require high concrete placement rates or where access is difficult.
- Reduced water demand: Lower water usage helps decrease cracks caused by rapid evaporation and increases concrete durability.
- Reduced efflorescence: Through controlled hydration and reduced ions, it prevents the formation of white spots on the concrete surface.
- Greater bond between concrete and rebar: Stronger adhesion to reinforcement bars improves tensile strength and structural integrity.
- Better retention in cement paste: This feature enhances chemical reactions and increases concrete strength.
- Higher chemical resistance: Especially provides more resistance to sulfates found in marine environments or aggressive soils.
