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.
