<p>A process for colouring concrete is based on the use of granular pigments as dies, with the exception of pressed and agglomerated granules. The granules used consist of one or several pigments and one or several binders which facilitate the dispersion of the pigments in the concrete, and possibly other additives. Said granules, in particular pearl granules, dissolve easily in the concrete mixer and are spread uniformly throughout the concrete.</p> |
