Cologne Group: The company's related products have been used normally in high-altitude areas.

On July 29, Cologne Corporation replied on the interactive platform that their products are already being used in high-altitude areas. The company's series of water reducing agents have not been used in the construction of hydropower stations in Tibet before, but are currently being used in the Sichuan-Tibet Railway project. The company's sales network has now expanded to cover Tibet, and some products are suitable for high-altitude, cold regions, with excellent early strength and abrasion resistance properties.
