Holcim Hydroport Bulk plant Lägerdorf

Holcim Hydroport is a Portland cement CEM I 42.5 N (hy) manufactured and monitored in accordance with EN 197-1. This cement is a hydraulically setting binder for the production of concrete and mortar. It consists of a mixture of finely ground, non-metallic inorganic constituents. After water is added to the cement, a suspension (cement paste) forms, which, due to the onset of the hydration reaction, sets and hardens both in air and under water and remains permanently solid. The composition of the product complies with the requirements of EN 197-1.

Holcim Hydroport 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 Hydroport, 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.

Holcim Hydroport is used as a binder in the manufacture of concrete and mortar.
