Abstract:

A process and equipment for producing multi-color concrete products, including architectural concrete blocks, concrete bricks, modular concrete products that are suitable for use in landscaping applications, such as retaining wall blocks, concrete pavers, and concrete slabs. The invention includes a spray mechanism that sprays liquid pigment onto concrete discharged from a hopper. The concrete then proceeds to a blending mechanism which blends the pigment into the concrete to produce a multi-color concrete blend. The concrete blend is then used to produce multi-colored concrete products.

Abstract:

A concrete block produced from a workpiece that includes at least a portion of a top surface that is roughened by a roughening assembly. The roughening assembly may include a shaft having a plurality of roughening members, the shaft being rotated in a direction opposed to the movement of the workpiece. A splitting mechanism is provided downstream of the roughening assembly to split the workpiece into one or more blocks. The blocks may be placed in a wall having a setback, with the roughened top surface of each block enhancing a natural appearance of the ledge created as a result of the setback.
