Colored Concrete – Colorant is added to concrete during the mixing process produces uniform tinting throughout the slab and consistent results from batch to batch. The colorant may be in liquid or powder form. For small projects, home centers or concrete-product retailers may carry bottles of liquid colorant which can be added to bags of ready-mix. For larger flatwork projects like foundation slabs, walkways, patios, or driveways, bags of powdered water-reducing color admixtures can be ordered at the mixing plant. Admixtures are used to improve plasticity, workability, and to control set time. When pattern stamps are used, a longer period of workability may be needed to complete the process in large areas. Some manufacturers offer their products in pre-measured disintegrating bags designed to treat particular amounts of concrete. The unopened bags are simply tossed into the mixer with water and aggregate prior to adding cement and sand. When pattern stamping is planned, integral colorants may serve as a base tone that can be modified by color hardeners and release agents to achieve a more mottled natural look.
