Manufacturing method for multi-colored high-strength concrete products with sharp-contoured color transitions, involves connecting multi-colored concrete mechanically during hardening in grout casting mold

摘要

The method involves connecting multi-colored concrete mechanically during the hardening in the grout casting mold, which is fixed by different textures (semisolid or fluid) of mixing methods followed by each other. The specified sharp-contoured color transitions are maintained properly. The reaction entails an exotherms running off during the fast hardening by precipitation of the hard gypsum, which accelerates hardening by precipitation of the total concrete product.
