A device for the manufacture of flowing foam is disclosed. It comprises a support (1) with feed grooves (2,5) for sand and cement with feeding screws (3,6), driven by speed regulated motors (4,7), a third feed groove (8) with a third feed screw (9) driven by a third speed regulated motor (10) for the reception, mixing and transfer of sand and cement. Furthermore there is a first capacity regulated pump (11) for the feed of water, partly to the third feed groove (8) and partly to a first mixer (12) for mixing with a surface active component, feed by a second capacity regulated pump (13) and mixing with air feed by a first capacity regulated valve (14) for feeding of air into a second mixer (15) to form a foam. The device is primarily characterized in that a computer with a memory is in such controlling connection with said motors (4,7, 10, 17), the pumps (11, 13) and the valve (14), that the capacity of these and thus the proportion of sand, cement, water, surface active component and air is settable according to a chosen recipe among several recipes, programmed in advance in the memory of the computer ( 19). The mass flow giver (33) admits that the device operates independent of the pressure of the pressurized air after the compressor (20).
