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.
In a precast reinforced concrete wall, the improvement comprising, a monolithic surface ornamentation including a plurality of grooves cast in at least one external surface of said concrete wall, said at least one external surface having vertically oriented side portions and a horizontally oriented top portion, a plurality of sectors spanning the spaces between said grooves, a plurality of layers of pigmented cements, one layer of pigmented cement each filling said sectors spanning the respective spaces between said grooves and with each said pigmented cement being monolithically joined to the concrete wall,
In a precast steel reinforced concrete barricade comprising an integrated massive concrete slab having steel reinforcing means therein and at least one vertically oriented side portion beginning from a relatively wide base portion which extends upwardly to a relatively narrow horizontally oriented top portion, the improvement comprising,
