Method for applying coating concretes of high adhesion to old-concrete surfaces

摘要

The invention relates to a method for applying coating concretes of high adhesion to old-concrete surfaces. This method involves the mechanical production of thin large-area concrete coatings. The invention finds advantageous application, inter alia, in the restoration of air-traffic, road-traffic and parking surfaces. According to the invention, following a surface-condition and characteristic-value analysis of the old concrete, its pretreatment (milling of, removal of a very thin layer), including mechanical application of an aqueous inorganic saline solution to improve the adhesion, and the application of an adhesive bridge, the coating concrete is applied by means of height- and direction-guided slip form paver and aftertreated by means of a film-forming aftertreatment medium.
