Abstract (en)
[origin: WO0029679A1] A concrete slab (1) with internally cast ducts (2) for circulating gas, preferably air. The ducts are arranged in a predetermined spaced-apart relationship over the extent of the concrete slab and connected to at least one inlet (6) and one outlet (7) for the circulating gas. Furthermore, the ducts (2) communicate directly with the surrounding concrete (3) to allow migration of substances from the concrete (3) into the ducts (2) and removal of the same by means of the gas circulating in the ducts (2) as well as migration of substance in the gas circulating in the ducts (2) into the concrete (3). The invention also relates to methods for producing said concrete slab.
