In concrete elements such as facade, wall and floor slab panels, the concrete front panel and rear panel alone are mutually fastened by an intermediate thermal insulating layer of mineral fibre aggregate. The concrete and insulating fibre aggregate are worked into one another in the boundary layer such that the concrete (cement paste) being worked into the insulating fibre aggregate achieves a suplementary high fibre concentration. This combined with using insulating fibre aggregate being laminated and having a high density has the effect that the forces from the front panel can be transferred to the rear panel such that by this method a stressedskin construction is created. Front and rear panels are made as fibre-reinforced concrete (cement mortar) in thicknesses of the dimensions approx. 1-3 cm and with fibres of polypropylene or a corresponding chemical, and possibly also with mineral fibres. The construction is thus totally without steel such as reinforcements or anchors between the concrete panels like in the prior art panels of the conventional concrete elements. |
