  • the metering device for filling the plastic molds is equipped with at least one metering tube, which is flush arranged at a certain angle to the horizontal plane on a full plate. It is advantageous for the present invention that the readily flowable concrete is not subjected to any mechanical compaction in the molds. Another advantage is that the concrete mixture is added a superplasticizer for self-compression.
  • the self-compacting concrete mixture is added via a metering a coloring substance in order to obtain certain surface effects, such as marbling or heraldic sign.
  • a further advantage of the method according to the invention is that the curing process in which the concrete reaches the effective concrete age (t ") for further mechanical processing is approximately between 0.5 and 1 day, which corresponds to a relatively short period of time.
  • the time until the effective concrete age (t w ) is reached depends inter alia, in particular, on the ambient temperature and the composition of the concrete mixture.

  • the filled plastic molds 9 remain until they have reached a predetermined degree of ripeness, that is, a certain effective concrete age (t w ). If the concrete hardens under normal temperatures (about 20 0 C), the effective concrete age (t w ) corresponds to the true concrete age (t). In the case of deviating, changeable temperatures, the effective age of the concrete takes the place of the real age.
