Blastfurnace Cement CEM III A + SR 42.5 N
This is manufactured to comply with the requirements of BS EN 197-4:2004 strength class 42.5 L and ASTM C 595-08 type IS. It typically has Blastfurnace Slag content 50%.
Blastfurnace Cement contains a controlled blend of Portland Cement and Ground Granulated Blastfurnace Slag. It is recommended as an alternative to CEM I Portland Cement for most applications including civil engineering projects, buildings, ready- mixed concrete applications and concrete projects.
Blastfurnace Cement concrete compared with CEM-I Portland Cement concrete are:
Improved workability retention.
Recommended for use with high reactivity aggregates.
Slightly lighter in colour which gives a more aesthetically pleasing concrete finish.
Significantly improved durability.
Reduced early age temperature rise.
Greatly reduced carbon dioxide emissions during manufacture.
