Abstract
A concrete slab for forming blocks for a retaining wall comprises a prism having parallel top and bottom surfaces, and opposed parallel side walls, and end walls, the prism has an X axis in the longitudinal direction extending between the end walls, a Y axis in the width direction extending between the side walls, and a Z axis perpendicular to the X and Y axes extending between the top and bottom surfaces. A first dividing line extends parallel to the X axis from one end wall to the other end wall in order to define a separating plane bisecting the prism. At least a pair of dividing lines extend parallel to the Y axis of the prism from the first dividing line to each of the opposite side walls, wherein the second dividing lines are parallel to each other but offset therefrom, whereby upon separating the slab along the first and second dividing lines, at least four blocks in the form of rectilinear prisms having different dimensions in the X axis will be formed. A molded block for a retaining wall is also defined having tapered end walls that are tapered and ears project from these end walls, parallel to the X axis and adjacent the rear wall.
