Abstract

The invention concerns a device for mixing/homogenizing fresh concrete with an admixture, preferably concrete matrix with foam to form foam concrete, in connection with transportation of concrete in a pipeline. In accordance with the invention the device comprises, in combination, at least one helical vane (21) extending in the pipeline interior along part of the longitudinal extension thereof, said vane delimiting, between neighbouring vane helices or windings, a concrete passageway, and a flow interference member (22) adjoining said helical concrete passageway.
