<p>A process for the coloring of concrete comprises an automatic programmable plant in which, from some microbatchers (2), the batches of coloring products are weighed with an electronic balance (5) which supports a conveyor belt (3) used to discharge said batches in a container (6) with mixer (7) with motor (8). In the container (6) the batches of colorants are prediluted in water then discharged in the concrete mixers in which the concrete mixed with the necessary aggregates is already present. A second batch of water, useful to complete the final mix of colored concrete, is subsequently discharged in the container (6), along the drain valve (12), the suction pump (13) and the channel (11) with the main object of washing the plant and preparing it for the following mixing operations, possibly different as regards batches and/or components.</p> |
