The outlet pipe having a compressed air connector for connection to a compressed air source. The upper surface of the drum rotor adjoins a gasket having one or more openings fixed to a clamping plate. The lower surface of the drum rotor adjoins a gasket which is fixed to a base plate. The hopper and the outlet pipe being spaced such that a chamber which communicates directly with the hopper can be moved so that it no longer communicates with the hopper but communicates with the outlet pipe. The clamping plate has a compressed air connector for blowing the dry mixture out into the outlet pipe. And an opening for allowing compressed air to escape from the chambers, which opening is located between the position when the chamber communicates with the outlet pipe and the position when it communicates with the hopper outlet. A connection is provided in the upper gasket which connects to at least one chamber empty of concrete and one chamber containing concrete to equalize the pressure between the chambers.
