Rapid Cement
Composition
- Portland clinker in the amount of 95-100%
- Secondary ingredients in the amount of 0-5%
- Setting time regulator - calcium sulfate
Characteristics
- Specific gravity 3.10 kg/dm3
- Volume of 100 kg of cement is 32.3 dm3
- Bulk density 1.42 t/m3
- Rapid strength gain
- High heat of hydration
- High early and final strength
Application
- High-strength concrete - HSC
- Self-compacting concrete - SCC
- Ordinary concrete, commercial according to EN 206-1 class C16/20 and higher
- Concrete for vibro-pressed prefabricates e.g. concrete paving blocks
- Concrete for monolithic structures and elements
- Cementitious and cement-lime building mortars: 'masonry and plastering'
