Abstract
A method of making a concrete block having decorative stones embedded in a surface thereof includes the steps of placing on a face plate a layer of stones which includes a plurality of spaced decorative surface stones and includes filler stones substantially smaller than the surface stones and disposed in the spaces between the surface stones, applying a cement mortar on the surface stones and filler stones, introducing concrete into a separate mold, inverting the face plate and placing it on top of the concrete in the mold, consolidating the concrete and assembling the concrete and the sruface stones by applying pressure and vibration, removing the mold and the face plate, and curing the resulting block without the mold.

A method of manufacturing a concrete block having decorative surface stones embedded in a surface thereof;
- comprising the steps of:
- placing on a face plate a layer of filler stones, inserting decorative surface stone partially into said layer of filler stones, said surface stones being spaced from each other and having sizes substantially larger than the sizes of said filler stones, applying a layer of a cement mortar over said surface stones and said filler stones, introducing concrete having a slump value of substantially 0 cm into a separate mold, inverting said face plate having said stones and mortar thereof and placing same on the top of said concrete in said mold, applying pressure and vibration to said concrete and stones to consolidate said concrete and to assemble said concrete and said surface stones, removing said mold and said face plate from said assembled concrete and surface stones after said step of applying pressure and vibration, and thereafter curing the resulting concrete block having said decorative surface stones embedded in a surface thereof without said mold.
A method of manufacturing a concrete block having decorative surface stones embedded in a surface thereof, comprising the steps of:
- placing decorative surface stones with spaces therebetween on a face plate, filling said spaces between said surface stones with filler stones of a size substantially smaller than said surface stones, applying a layer of a cement mortar over said surface stones and said filler stones, introducing concrete having a slump value of substantially 0 cm into a separate mold, inverting said face plate having said stones and mortar thereon and placing same on the top of said concrete in said mold, applying pressure and vibration to said concrete and stones to consolidate said concrete and to assemble said concrete and said surface stones, removing said mold and said face plate from said assembled concrete and surface stones after said step of applying pressure and vibration, and thereafter curing the resulting concrete block having said decorative surface stones embedded in a surface thereof without said mold.
