In the production of fresh concrete, the right color shade is essential. To mix this, fast, accurate and clean metering of the pigments is required. A new generation of water-soluble bags has been developed for this purpose. The bag is pre-packed and is added during the mixing process. During processing, users do not come into contact with the powder pigment, so they are protected from particles. The total package dissolves without residue during processing.
While the concrete truck is on its way to the construction site, the ready-to-use fresh concrete is already being mixed in its drum. The new water-soluble bags are ideally suited for coloring this so-called ready-mix concrete as well as precast elements. They contain pigments that mix with the cement mixture after the packaging has dissolved without leaving any residue. In contrast to liquid colors, no additional water is added and there is no need for time-consuming mix optimization. In addition, the bags ensure clear storage logistics: the transport of water components and the storage of empty containers are eliminated. The soluble bags thus represent a cost-effective alternative to liquid inks.
