The invention relates to a method for producing a composite material from cement stone, aggregate and reinforcing means. Cement stone is produced by providing a starting product comprising at least 20% by weight of one or more of the following constituents: ultramafic rock, weathering products of ultramafic rock, olivine and/or industrial waste; homogenising the starting product and hydrothermally treating the homogenised starting product in a thermal treatment apparatus at a temperature of above 100°C for at least 12 hours. Furthermore, the converted starting product is dewatered to remove bound water by thermal treatment and/or reactive grinding. Then, the converted, dewatered starting product is used as a binder, and for hardening, setting water is added, the water/binder ratio being 1:2 or less. Before, after and/or at the same time as the setting water is added, an aggregate and reinforcing means are added to the converted, dewatered starting product in order to increase the load-carrying capacity, the reinforcing means being resistant to pH values of below 11 and/or having protection against pH values of below 11. In addition or as an alternative, means for raising the pH value of the porous solution of the cement stone can be added to the starting product of the cement stone.

The invention relates to a method for generating a signal that represents a signal value between previously captured data values. The method starts with the capture of a multi-dimensional data set from numerous data by means of a capturing unit. Subsequently, the data set is broken down into numerous multi-dimensional data blocks and the data blocks are filled on exactly one predefined side per dimension with data values from the data block adjoining said side. Thereafter, the filled data blocks are stored as code words in a code book. Finally, a desired position in a code word for which no data value is stored is queried, an interpolated data value for said position between data values adjacent to the queried position being determined, provided that adjacent data values are present in each dimension on both sides of the queried position, or the desired position in a code word adjacent to the initially selected code word is queried, provided that, at the position in the initially selected code word, an adjacent data value is absent on at least one side. In conclusion, the interpolated data value is output to a signal-generating unit, which generates a signal corresponding to the data value.
