General comment on data set | Holcim Sulfo 5 R ist ein Portlandzement CEM I 52,5 R-SR3 (na) der gemäß EN 197-1 bzw. *DIN 1164-10* hergestellt und überwacht wird. Dieser Zement ist ein hydraulisch erhärtendes Bindemittel zur Herstellung von Beton und Mörtel. Er besteht aus einem Gemisch fein aufgemahlener, nichtmetallisch-anorganischer Bestandteile. Nach Zugabe von Wasser zum Zement entsteht eine Suspension (Zementleim), die aufgrund einsetzender Hydratationsreaktion sowohl an der Luft als auch unter Wasser erstarrt und erhärtet sowie dauerhaft fest bleibt. Die Zusammensetzung des Produkts entspricht den Vorgaben der EN 197-1. | ||||||||||||||||||||||||||||||||||||

Technology description including background system | Holcim Sulfo 5 R is manufactured at the Lägerdorf plant. Production of Portland cement clinker Limestone, marl, clay or their natural mixture, are required for the production of Portland cement clinker. These starting materials are mined in quarries, pre-crushed and transported to the nearby cement works. There they are homogenized into an intermediate product, with additional natural or secondary corrective substances being added to fine-tune the chemical composition. In the subsequent heating process, the Portland cement clinker is produced from the intermediate product. The firing process takes place in a rotary kiln, where the material is thermally converted at around 1450 °C and then rapidly cooled. The finished clinker is stored in silos. Cement Production To produce the ready-to-sell cement Holcim Sulfo 5 R, the Portland cement clinker is ground into a fine powder. A sulfate carrier is added to control the setting behavior. The Lägerdorf plant is ISO 9001 certified. | ||||||||||||||||||||||||||||||||||||
