Cement free concrete

Byrne Bros. successfully used 24m³ of cement-free (Cemfree) concrete as structural backfill between perimeter liner walls and neighbouring basements on the iconic Scalpel building.

Although only 24m³ of Cemfree was used this resulted in a saving of over 3T of CO2, compared to an equivalent mix using 50% CEM I with 50% GGBS replacement.

This is the first time ever that a cement free concrete has been used in the permanent works of a project in London, which is an historic milestone, and it’s a precedent for future projects.Cement free concrete
