Theoretical prerequisites for the use of recycled aggregates in concrete mixes and concretes

Abstract

The purpose of the study is to determine the prospects of using recycled concrete structures for the preparation of concrete mixes and concretes. The conducted theoretical studies give reason to claim that a significant part of recycled aggregates can be reused not only as backfill during the restoration of damaged objects, but also in the production of building materials. However, in order to expand the amount of waste that can be processed for reuse, it is necessary to conduct a number of studies on the influence of organic residues, combustion products on the properties of concrete mix and concrete
