Its natural mineral raw material base makes it useful, long-lasting and recyclable. On base of the raw material calcium carbonate ZKW Otterbein produces various cement products with excellent structural engineering characteristics, e.g. portland cement and blast furnace cement. Modern production facilities and up-to-date technology ensure a constant high production quality (06/2011).
