Building Cement
Composition
- Portland clinker in the amount of 65-79%
- Fly ash silica and limestone aggregate in a total amount of 21-35%
- Calcium sulfate as a setting time regulator
Characteristics
- Specific gravity 2.93 kg/dm3
- Volume of 100 kg of cement is 34.1 dm3
- Bulk density 1.35 t/m3
- Moderate strength development dynamics
- Moderate heat of hydration
- Good workability and plasticity of concrete mix
- Optimal retention time of working properties of concrete mix
- Very good adhesion to the substrate (significant reduction in the need for hydrated lime in the production of mortar and plaster - cost reduction of mortar production)
- Low shrinkage
Application
- Ordinary concrete, commercial according to PN-EN 206-1
- Cement and cement-lime building mortars: "masonry and plastering"
- Concrete for large and small prefabricated products
- "Lean" concrete for substructures of load-bearing structures
