Variants of the integrated use of construction waste–aggregates made of crushed materials–in the production of small architectural forms and other decorative products from self-compacting concrete are considered. It has been established that the aggregate grains from crushed concrete do not interfere with the high fluidity of the concrete mixture with an optimal amount of cement paste. In the production of decorative self-compacting concretes, the decisive technological factor is the use of the super water-reducing additive MasterPolyHeed 3545. The rheological compatibility with white cement and the high potential of the additive are realized due to the unique polymer structure, in which the rigid linear interaction of the polycarboxylate backbone with the cement surface is compensated by the flexible bulk action of polyaryl ethers. Evaluation of the decorative properties of concrete showed that the orange Bayferrox pigment in the amount of 2% of the cement mass gives the concrete a light terracotta color, but with an increase in consumption up to 4%, it leads to a drop in concrete strength by 8%. It has been established that the use of crushed fine-dispersed material (brick dust) as a mineral dye gives the concrete a weakly expressed terracotta color.
