SUMMARY OF THE INVENTION The invention relates to, on the one hand, a method and on the other hand, a device for the rapid hardening of concrete and similar casting materials by carbonation. The method is characterized by forcing the capillary system of the material in the curing facility to be effectively dried out; prior to and/or during carbonation, by means of controlled conditions in the form of an air flow, heat generation and moisture absorption in a circulating, continous procedure. The device for applying the afore described curing process is characterized by a hermetically closed unit which contains equipment for air circulation, heat generation as well as a control device for conditioning, connected to the close unit, by which the equipment units may be run individually or jointly, depend- ing on the composition, structure, geometry, etc. of the material to be cured. Vacuum suction may also be connected to the device by the curing facility, when ever vacuum treatment is possible, i.e. in the case of a closed mould or a closed chamber. Total de-humidification of the casting material can take place provided air circulation, heat supply and de-humidification occur in a, with the casting material, completely closed system.
