Plasterable precast concrete compound unit and process for the production thereof

摘要

A description is given of a precast concrete compound unit having a plasterable fair face, the plastering capacity being achieved in that the fair face is provided with a multiplicity of regularly distributed, small-surface-area depressions for anchoring the plaster. In order to produce these small-surface-area depressions, use is preferably made of a commercially available air-cushion film.
