Granulated Blastfurnace SlagSecretary:FEhS – Institut fuer Baustoff-Forschung e.V.Bliersheimer Strasse 62, D-47229 Duisburg-Rheinhausen, GermanyPhone ++49/2065/9945-0 Fax ++49/2065/9945-10E-Mail info@euroslag.org Internet: http://www.euroslag.org• Grout: Grouts containing slag have been used on manyoccasions to control temperature rise during hydration andin areas of aggressive conditions.• Aggregate: Unground GBS is suitable as a normalweight aggregate in concrete.• Road Making: Unground GBS can be used as abase layer material in road construction.Environmental BenefitsIn Europe the production of 1 t Portland cement generatesabout 1.2 t CO 2on average, while the production of 1 tblast-furnace slag cement containing 50 wt.-% GGBS generatesonly 0.54 t CO 2. These data include emissions fromthe calcination process, the fossil fuel burning, and the use ... 6 weeks laterof electricity. For some countries maybe the potential savingis much more higher. Thus the use of slag is a very effective and economicmethod to reduce the energy consumption and the CO 2-emissions inherent incement production.Beyond that mortar and concrete made with GGBS have a lower content ofChromium-VI, which can be responsible for skin irritations of workers handlingthe material manual without any skin protection.More informationsFresh concrete surface ...The literature on GBS is very extensive. Therefore only three examples forimportant standards are listed:• European Standard EN 197-1: Cement - Part 1, Composition,specifications and conformity criteria for common cements (2000)• British Standard BS 6699: Ground granulated blastfurnace slag foruse with Portland cement (1992)• ASTM C 989: Ground granulated blast-furnace slag for use in concrete andmortars (1999)About EUROSLAG:In 2000 slag producers and processors in Europe have come together to formEUROSLAG, the association of organisations and companies concerned with all aspectsof the manufacture and utilisation of slag products. It seeks- to promote and develop the utilisation of slag in all appropriate situations- to ensure slag products are made by the best possible processes- to provide and encourage communication between slag producers and processors- to co-ordinate technical working parties and research and development- to bring together people from both the supply and utilisation side of the industry- to provide a co-ordinated approach to European Standardisation.© 2003Health & Safety Information:CAS 65996-69-2, EINECS 266-002-0, EU safety data sheets 401/402
