This means significantly reducing Portland cement batches by using secondary raw materials with pozzolanic properties such as finely ground concrete or brick dust. Further reduce the consumption of natural aggregates by replacing them with recycled concrete or brick. An important factor in the experimental verification of concrete recipes will be, in addition to achieving the required physical - mechanical properties, also proving their longevity for operation in various aggressive environments.
