Abstract: Portland-slag cements have been manufactured in the UK since 1914, but were never widely used. Instead, a practice has developed where separate ground granulated blastfurnace slag (GGBS) is added at the concrete mixer as an addition. Generally, it comprises between 25% and 70% of the binder, with Portland cement comprising the remainder. Many of the ready-mixed concrete plants in the UK have a silo containing GGBS.
This paper describes the development of the use of GGBS and the parallel evolution of relevant British Standards. Details are given of the conformity testing procedure which has to be satisfied for GGBS to count fully towards the ‘cement content’ in concrete.
