摘要

Device for effecting protective treatments on manufactures in concrete constituted of the combination in a single apparatus of a panel for the heating of the surface to be treated provided with means for establishing on the surface itself a constant flow of hot air with the possibility to regulate the temperature, and of an assembly being apt to impregnate with a catalyzed monomer the surface of the already heat-treated concrete and to polymerize with hot water the catalyzed monomer once it has been absorbed by the manufacture itself.
