Abstract
Cellular lightweight concrete slabs are manufactured by cutting a still plastic block of cellular concrete mass resting on a first support horizontally into slices which are then moved over one by one to a second support and piled in reversed order thereon, at least one of the two broadsides of each body slice being subjected to a treatment before being covered by the next transferred slice. The treatment prevents the body slices from cementing together during the subsequent steam-hardening process and may also improve the quality of the slabs when hardened. An apparatus for such manufacture features a movable suction head for transferring the body slices as well as associated means for cutting and treating said slices.
