PROCESS FOR PRODUCING PIGMENT GRANULES AND FOR DYEING CONCRETE

摘要

Process for producing pigment granules comprising the following steps of: a) preparing a mixture, in the form of a liquid suspension, of an emulsion and/or of a paste, said mixture comprising at least one pigment and at least one binder selected from the group constituted by the organic compounds which form insoluble films after drying and/or by chemical reaction during the drying, each binder being selected so that the films thereby obtained are free of dispersing effect in concretes; and b) drying of said mixture. The granules obtained are resistant to humidity and are used for dyeing concretes.
