After delivery of the desired batch of concrete or after completion of the continuous delivery process, the mixing device is cleaned and is thus ready for the next use or preparation of the next batch.
  • the invention also makes it possible to deliver smaller batches to different construction sites, which in turn considerably reduces the delivery costs for the concrete.
  • the invention is characterized in that the ready-to-install preparation of the binder / aggregate mixture on site, i.

  • An essential aspect of the invention is that the binder / aggregate mixture delivered by the transport vehicle is not yet ready for setting, which is why it can be transported for any length of time without the processing quality of the mixture being impaired by interim setting during transport.
  • the construction site is free to choose the addition of setting accelerators and the mixture can be better tailored to the processing needs at the construction site.
  • preferential a container and a metering device for the accelerator are also provided on the transport vehicle.
  • the new technology also makes it possible to deliver the concrete in small batches to several construction sites, which are then mixed on site ready for setting.
  • the mixing device for mixing the mixture ready for processing does not have to be coupled to the transport vehicle, but can also be provided at the construction site.
