| 摘要 |
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 DEG , to the further support surface on which surface the transferred slabs are placed on one long-side edge thereof in mutually spaced apart relationship. |
