ABSTRACT:
In a concrete pump for wet spraying, in which standard concrete is pumped to a mixing jet, compressed air and if necessary a hardening accelerant are mixed into the concrete stream, which is applied with the jet and compressed; it is the purpose of the invention in its initial version on the one hand to minimize the fine dust yield at the jet, on the other hand to guarantee the availability of the amount of compressed air needed for the wet spraying process, characterized by a regulating section (20) in which the capacity of the concrete pump (1) forms a standard volume for monitoring the amount of compressed air flowing to the mixing jet (3) in such a way that the relationship of the amount of compressed air mixed in per unit of time to the amount of concrete pumped in per unit of time corresponds to a desired value which produces the smallest fine dust yield when the concrete is applied.
