RESEARCH INTO THE POSSIBILITIES OF USING RECYCLED WASTE AS COMPONENTS OF CONCRETE MIXTURES IN THE CONTEXT OF SUSTAINABLE CONSTRUCTION PRINCIPLES

Abstract

The large-scale destruction caused by Russian aggression creates not only a humanitarian catastrophe, but also a serious environmental problem. The huge volumes of construction waste generated as a result of such events require effective disposal. One of the promising areas is the use of this waste in concrete mixtures. This approach allows you to reduce the volume of waste in landfills, preserve natural resources and promote the development of sustainable construction. Since just to restore the lost stock of buildings and structures, a huge amount of building materials will be needed. Numerous experimental studies are being conducted to assess the possibilities of using secondary building materials in concrete. Scientists are studying the impact of various types of waste (concrete, brick, asphalt) on the properties of concrete, such as strength, water resistance, frost resistance, corrosion resistance, and others. The paper considers the possibilities of creating new composite materials that use recycled aggregates. Since recycling is considered one of the best options for processing construction waste. The prospects for the development of technologies for the use of recycled waste as components of concrete mixtures in the context of the principles of sustainable construction and the concept of reconstruction of Ukraine are analyzed. In addition, a feature of the Ukrainian experience in the use of recycled waste will be the potential presence of residues of organic substances and combustion products as a result of military operations, which significantly complicates the development of structural formation of concretes based on such material. This study can stimulate the development of the construction industry, opening up opportunities for the processing of significant volumes of waste resulting from military operations, and also allows increasing the diversity of concrete production for various purposes.
