Sposób wytwarzania kostki brukowej polega na tym, że przygotowuje się mieszankę betonową, którą napełnia się formę wibroprasy i napełnioną formę poddaje się jednoczesnemu prasowaniu i wibrowaniu, kształtując surowe kostki brukowe. Po napełnieniu formy wibroprasy na mieszankę betonową natryskuje się wodny koncentrat nanomiedzi o wielkości cząstek od 25 nm do 35 nm, w ilości zapewniającej stężenie cząstek nanomiedzi w górnej warstwie kostki o grubości co najmniej 1 mm na poziomie co najmniej 20 ppm.The method of producing paving stones consists in preparing a concrete mix, which is filled with a molding machine and the filled mold is subjected to simultaneous pressing and vibrating, shaping raw paving stones. After filling the vibro-press mold, an aqueous concentrate of nanocopper with a particle size of 25 nm to 35 nm is sprayed onto the concrete mix in an amount that ensures the concentration of nanocopper particles in the upper cube layer at least 1 mm thick at a level of at least 20 ppm.
