| 摘要 |
The invention relates to a multi-layer structure (1) especially used for supporting works (tunnels, screen walls, basement walls, etc.) constructed from the superposition of at least two compatible layers (2, 3) of CBC (cement-based composites), having different mechanical properties that enable a specific function to be fulfilled (insulant against fire, high resistance to impacts, impermeability etc.) or combined functions if necessary. Said concrete layers (2, 3 and 4) are moulded and joined in a single phase and in any case without using additional adhesive layers, at least one of said layers (2, 3 or 4) having structural functions. The main advantage of the invention is the synergy created using CBC layers (2, 3 and 4) having different mechanical properties, so that they can work in the most suitable manner, thereby providing structural elements that are much more efficient. |
