Abstract: A poured concrete wall construction. In forming the wall construction, a back panel is mounted on a foundation and a plurality of generally rectangular thin-walled blocks formed of crushed stone bonded with a thermosetting resin are stacked to form a wall that is spaced from the back panel with a cavity being defined between the stack and the back panel. A tubular frame is positioned outwardly of the stack, and a plurality of connecting members connect the back panel and the frame and extend through mating notches in the edges of adjacent the blocks. Clamps are connected to the outer ends of the connecting members to connect the connecting members to the frame. Concrete is subsequently poured into the cavity between the backing panel and the block stock to form the wall construction with the stack of blocks forming an outer decorative face for the wall.
