ABSTRACT:
A reinforced concrete wall, such as a road barrier or barricade, has a monolithic surface ornamentation thereon constituted by pigmented cements and grooves simulating mortar joints. In the horizontally oriented top portions of the wall where the pigmented cements are substantially thicker than the layers of pigmented cements monolithically joined to the vertical oriented portions of the wall so that these portions, which are subject to chipping and the like during handling and use will retain their aesthetically pleasing appearance. In the molding process, ribs on the mold surface which will form the grooves have a retardant applied thereto so that the cement forming the mortar joint will set at a slower rate than the rest of the body of the concrete wall and when removed from the mold can be brushed. When the wall is in the form of a road barrier, the ends are provided with a conical projection and a conical recess, respectively, to provide coupling between adjacent wall units.
