Abstract (en)
[origin: EP0900881A2] The construction material has acoustic protection surface (SO) which, at least in sections, has a coarse structure (QP) of alternating peaks (H) and valleys (T) at intervals in the cm range. It gives a fine gap structure (FS) with gap intervals and/or depths in a mm range or smaller. The acoustic protection zone has light concrete, in at least part of its vol., with a pore or bubble structure and/or with finely distributed light additives.
