ABSTRACT:
A concrete slab, and a building construction system employing the concrete slab, in which the slab is formed in a casting or extrusion process to include a plurality of longitudinally extending core passages, and a groove extending transversely across one end face thereof. A plurality of invention slabs are stacked side by side to form a continuous wall structure, a plurality of conventional cored floor slabs are arranged with their one ends supported on the upper ends of the invention wall slabs, and concrete slurry is poured into the interface between the wall slabs and the floor slabs to fill at least some of the vertical core passages in the wall slabs and at least portions of the horizontal core passages in the floor slabs to form a continuous reinforcing concrete frame within the wall and floor. The concrete slabs provide a form for molding the reinforcing concrete frame and also add significantly the overall strength of the wall by providing a rigid concrete bridging structure between the vertical columns and horizontal bond beams of the reinforcing concrete frame.
