Originální abstrakt

The problems of concrete recycling as a complex poly-reinforced composite characterized by unstable composition and properties are discussed. The peculiarity of recycling concrete scrap is that its return to the production cycle can be carried out in the form of different products: coarse aggregate (recycled aggregate), fine aggregate (sand from crushed concrete), as well as in the form of a dust-like fraction. It is shown that aggregates made of crushed concrete are inferior to natural analogues due to the presence of cement-sand mortar in their composition. Given the growing threat of depletion of natural resources, it seems appropriate to consider construction waste not only as secondary resources for the production of concrete and mortars, but also more widely: as a promising technogenic source of polymineral raw materials, including for firing technologies.
