Abstract
The present invention is concerned with a method of manufacturing porous concrete products in which there is first formed an at least approximately parallelepipedic body of concrete mass which is plastic at a given stage but still shape permanent, whereafter said body resting on a first support surface, while the concrete mass is still plastic, is divided into a multiplicity of slabs by means of horizontal cuts, the thickness of each slab being much smaller than the original height of the body, whereafter a multiplicity of the thus obtained slabs are charged to an autoclave in which they are steam-cured in a group resting on a further support surface. The invention is characterized in that one slab at a time is lifted from the remaining body resting on the first support surface and is transferred, while being turned through 90.degree., to the further support surface on which surface the transferred slabs are placed on one long-side edge thereof in mutually spaced apart relationship.
