Capabilities in blast-furnace cements

摘要

Around eighty engineers, concrete technologists, construction industry representatives and associates from research and education met on April 26, 2007 for the HOZ* Seminar, which has a long and rich history and generally takes place every two years (Fig. 1).They were attending the traditional event, which was held for the. first time by CEMEX at ThyssenKrupp Steel AG's Seminar and Conference Center in Duisburg. A series of nine papers provided them with information on current product developments, research results and potential applications for cements containing blast-furnace slag (GBFS). In addition, these specialists also had the opportunity of visiting the blast-furnace sand granulation facility at ThyssenKrupp's Schwelgern plant in the north of Duisburg. The conclusion reached by the participants: cements containing GBFS have attained lasting significance, due not only to their contribution to reducing CO_2 emissions and to general environmental safety, but also to their validated new potential applications.
