- Long curing times and a low hydration heat development make concreting easier, such as for floor slabs in the summer
- Suitable as a summer cement thanks to its moderate early strength development
- Suitable for alkali-sensitive aggregates
- Enables greater flexibility in the selection of aggregates
CEM II/B-S 42.5 N (na) is delivered as bulk in silo lorries.
