Reuse of concrete and brick scrap as aggregates

Abstract

The use of industrial waste as concrete aggregates solves the problem of recycling these wastes and simultaneously reduces the volume of natural stone materials extraction and, consequently, decreases the environment load associated with their extraction. The special military operation caused a large amount of concrete and brick scrap from the emergency buildings demolition. To substantiate the possibility of recycling the mentioned construction wastes by means of their application as concrete aggregates, the authors have reviewed research works in this area, made a plan of the experiment, determined physical and mechanical characteristics of rubble from the studied materials and cement concrete on its basis. The results of the experiment have been analyzed and conclusions about possibility to use concrete and bricks scrap as aggregates in concrete have been formulated.
