Technical evaluation for CEM Ⅱ/C-M in Italy

摘要

Buzzi Unicem has obtained technical evaluation certification for its CEM Ⅱ/C-M Portland composite cements produced in the Trino, Vernasca, Settimello, Guidonia, Barletta and Augusta plants. These are the new cements from the CGreen Line, which will allow the company to improve the "green footprint" of its product line and achieve the objectives set forth in the 2030 Roadmap. CEM Ⅱ/C-M cements will also significantly help reduce CO_2 emissions in concrete structures (up to 40% less CO_2 per ton than CEM Ⅰ cements), yet maintaining the equivalent technical performance as products with a higher clinker content. In the CEM Ⅱ/C-M cements various components, including several with hydraulic activity, replace part of the clinker (between 50% and 64% by mass): granulated blast furnace slag ("S"), fly ash ("V"), pozzolan ("P") and limestone ("LL") are all main constituents of the recipe.
