PROCESS FOR COVERING A PIPE WITH A HYDRAULIC SETTING COMPOSITION

摘要

A hydraulically setting mass having a small tendency to cracking and a felt-like structure when freshly mixed while showing no cracks or only microscopic cracks when in the hardened condition comprises essentially a fast-hardening hydraulic cement binder, water, alkali-resistant mineral fibers and additives. The freshly mixed mass is applied in a layer to the surface of a tube or the like, the applied mass is completely covered with a sheet and the mass is pressed against the surface with the sheet.
