Page 9 - ConcreCem - State of the Art

These tests show that concrete with 0,3% ConcreCem improves compressive strength after 48 hours with 35% compared to the reference mix.
This complies with the requirement mentioned in the European Standard EN 934-2, table 7 (“Specific requirements for hardening accelerating admixtures”).
