Abstract (en)

[origin: DE4412972C1] In a method for producing bodies of gas concrete or the like, in which firstly a pourable, curable slurry comprising the basic materials for the body is produced, then an expanding agent (foaming agent) is added and the mass obtained is poured into a moulding box (2), provision is made, in order to reduce the size and number of the air inclusions remaining in the finished gas-concrete body, substantially before the beginning of the rising process, for a screen arrangement (8) having a mesh size which entrains damaging inclusions to be drawn through the mass and out of the latter. <IMAGE>
