摘要：An apparatus is described for foaming a slurry made of sand, water and ahydraulic binding medium by adding a foaming agent with a cylindrical vessel () forreceiving the slurry and an agitator () revolving relative to the vessel about the vesselaxis. In order to provide simple constructional conditions it is proposed that the agitator
() comprises agitating units () distributed over the cross section of the vessel, whichagitating units each consist of a rotor parallel to the vessel axis with agitator rods ()between retainers () on the face side, which rods are distributed over the circumference,are parallel to the axis and can be driven in an alternating manner in opposite directions.
