A chamber (1) for hardening building materials comprises sheet metal elements which are insulated from one another and are built on a base plate (5) and which form walls (2) and a ceiling (3). The chamber can be manufactured and operated inexpensively and is suitable both as a curing chamber for concrete blocks and for building materials cured with CO.sub.2. To this end, it is proposed that the walls (2) and/or ceiling (3) consist of self-supporting, double-walled sheet metal elements (4) connected to one another in an essentially gas-tight manner, and that the double-walled sheet metal elements (4) of the supply and/or discharge and distribution a gaseous hardening medium from outside the chamber (1) into its interior.

A method for making a carbonated precast concrete product, includes: obtaining a mixture including at least one binder material, an aggregate, and water; molding the mixture into a molded intermediate; demolding the molded intermediate to obtain a demolded intermediate, the demolded intermediate having a first water-to-binder ratio; conditioning the demolded intermediate to provide a conditioned article having a second water-to-binder ratio less than the first water-to-binder ratio of the demolded intermediate; and curing the conditioned article using carbon dioxide at a pressure ranging from an atmospheric pressure to a pressure greater than the atmospheric pressure by at most 10% of the atmospheric pressure. Curing the conditioned article may be done within an expandable enclosure.

The invention relates to a device for storing objects under defined temperature conditions and humidity conditions. In particular, the invention relates to a device for curing objects made of concrete. The device has a shelving system having a plurality of shelf supports and a plurality of bearing elements for supporting shelves supported on the shelf supports and arranged one above the other in a plurality of levels, on which shelves the objects are stored. According to the invention, a flow pipe system for distributing supply air provided in a climate system is at least partially integrated into the shelving system. A plurality of shelf supports in this case are at least in sections at the same time downward pipelines of the flow pipe system that the provided supply air is able to flow through. As a result, condensation at the foot of the shelving system and thus corrosion is counteracted at the shelf supports, thus increasing the service life of the shelving system.

The invention provides novel apparatus and processes for gas flow and conditioning to achieve optimal CO.sub.2 curing of articles of composite materials (e.g., precast objects made of carbonatable calcium silicate-based cements), with solid interior or having hollow interior ducts, channels and chambers or otherwise being hollowed out, as well as the precast objects so made, which are suitable for a variety of applications in construction, pavements and landscaping, and infrastructure.
