Cementitious Slag Makers Association

The Cementitious Slag Makers Association (CSMA) is a Trade Association, which was formed in 1985 to promote the use of GGBS in the UK.

Ground granulated blast furnace slag 'GGBS' is a cementitious material whose main use is in concrete.

The activities of the CSMA include:

• Technical input into British and European Standards
• Co-ordination and dissemination of research and development
• Advice on existing and potential applications
• Representing views of member companies to Government
• Exchange of information with GGBS producers' world-wide

the River Thames at Dartford, where the 'cement' for all
