Apparatus for the preparation of mortar has a wheel-mounted frame for an elongated vessel which receives metered quantities of solid and liquid constituents from discrete feeding units. The vessel has an outlet and contains a rotary homogenizing and evacuating device which mixes the solid and liquid constituents to form mortar and advances the mortar toward and through the outlet. Mortar issuing from the outlet of the vessel can be discharged into a separate container which is mounted in or on the frame and is connected with one or more evacuating pumps, into wheelbarrows or into the container of a conventional mortar mixing machine. The feeding unit for solid constituent may receive material by gravity flow or under the action of a rotary screw in a receptacle which is mounted in the frame at a level above the vessel and receives solid constituent from a pneumatic conveyor. The quantities of mortar in the container and of solid constituent in the receptacle are monitored by discrete detector means which arrest one or more prime movers for the moving parts of the apparatus when the quantity of mortar in the container or the quantity of solid constituent in the receptacle exceeds a predetermined quantity. The rates of admission of constituents into and of evacuation of mortar from the vessel are selected in such a way that the vessel contains a constant supply of mortar but is not filled to capacity.
