METHOD AND AUXILIARY AGENT FOR PRODUCTION OF CONCRETE ARTICLES, IN PARTICULAR CONCRETE SEMI-FINISHED PRODUCTS AND/OR CONCRETE SURFACES, AND AUXILIARY AGENT FOR PRODUCTION OF CONCRETE SURFACES

摘要

The aim of the invention is to simplify the production of concrete surfaces by means of displacers (240). To this end, the displacers are embodied e.g. as plastic balls (240) or plastic shells, and are locked in lattices (230) which are open on one side, preferably downwardly, and said modules can then be pressed into a first or second concrete layer that can already contain a first reinforcement mesh. The thus produced semi-finished product can then be covered with a concrete mass during the subsequent finishing process.
