The GGBS concrete was designed to be used as both C40 and C45 concretes with a high workability of 200 mm slump. To achieve low carbon footprint, the GGBS content was set at 50% of the total cementitious materials. In other words, the GGBS was added to replace 50% of the cement so as to reduce the cement content by one-half.
