Abstract (en)
[origin: EP0603640A2] German Offenlegungsschrift 40 20 124 indicates that even forming boards made of plastic must have such a low coefficient of thermal conductivity that the setting concrete can cool down. If turning chips are used, these must be chemically cleaned since they have come into contact with lubricating drilling fluid. In addition, chips require an adhesive bridge to the plastic. The invention would like to avoid this type of pretreatment of the metal bodies. To do this, the invention uses ground foil shreds, where "ground" has a meaning in the sense of the technique of "cutting mills" or "cutting granulators". <IMAGE>
