CEM II/A-S 52,5 R (sp) is a Portland-slag cement according to DIN EN 197-1. It is produced by the joint grinding or mixing of Portland cement clinker, granulated blastfurnace slag and specially selected sulfate carrier as solidification regulator.
Portland-slag cement CEM II/A-S 52.5 R (sp) is a special cement that meets the particular requirements for the production of concrete by the wet-spraying method. It is used in wet-sprayed concrete to secure tunnels excavated by mining methods and to secure slopes and excavation pits in civil engineering.
- Very good concrete workability
- low rebound
- economical shotcrete formulations due to low additive dosage (accelerator)
CEM II/A-S 52.5 R (sp) is delivered loose in silo trains.
