By means of suitable synthetic resin adhesives, storey-high slabs of reinforced autoclaved aerated concrete (AAC) can be joined to form transportable room size wall units within very short time. By means of the adhesive joints, the slabs are combined to form monolithic wall panels, which can be transported to the building site as soon as about 30 minutes after the glueing. Tests have been made with adhesives based on epoxide resins, polyurethane and polyester resins. All three kinds can be used in principle and the polyester adhesive has proved to cure faster than the others. The adhesives may also be used to glue AAC to reinforced normal-weight concrete and to steel. This permits lintels made of reinforced normal-weight concrete to be glued into the units over window and door openings. The safety in handling is improved in that steel rods extending horizontally at right angles through the surfaces defining the joints are fixed by nuts to the units. Said steel rods are intended only to prevent a fracture of the units in case of unforeseen shocks and of a possible failure of the adhesive joints as the units are handled and installed in the site.
