A process for the preparation of a hydraulically bound thin flat protective layer for the repair of damaged concrete structures, in particular of steel concrete constructions

摘要

The invention relates to a method for production and processing of a cement-bonded protective layer for the repair of damaged concrete structures, in particular of steel concrete constructions. Dollars a of the invention the object of the invention is a disadvantage of the prior art owing to eliminate the content of the patent claims. In particular state of the present invention to provide a hydraulic thin surfaces renovation mixture with a high tightly - and adhesion to develop. Dollars a this is achieved according to the invention in that the cement-bound protective layer as a carbon dioxide - and / or moisture barrier with the use of a grind - mixture in a layer thickness of 3 - 8 mm to the damaged or carbonated concrete surfaces is applied, wherein the particle fraction of the binder, 1 mu m, is strongly increased and the particle fraction of the binder to 10 mu m compared with conventional cement is reduced, so that by means of a targeted reduction of the capillary - and, on the one hand, a diffusion gelporengefüges reduced, and on the other hand an additional subsequent real calibrating process is achieved to the right.
