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.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Применение отходов промышленности в качестве заполнителей в бетон позволяет решить проблему утилизации этих отходов и одновременно снизить объемы добычи природных каменных материалов и, как следствие, уменьшить нагрузку на окружающую среду, сопряженную с их добычей. В связи с проведением специальной военной операции образуется большое количество бетонного и кирпичного лома от сноса аварийных зданий. Для обоснования возможности утилизации указанных строительных отходов путем применения их в качестве заполнителей в бетон авторами был произведен обзор научных работ по данному направлению, составлен план эксперимента, определены физико-механические характеристики щебня из исследуемых материалов и цементобетона на его основе. Проведен анализ результатов эксперимента и сформулированы выводы о возможности применения бетонного и кирпичного лома в качестве заполнителей в бетон.</p></trans-abstract><kwd-group xml:lang="en"><kwd>concrete aggregates</kwd><kwd>concrete scrap</kwd><kwd>ceramic brick scrap</kwd><kwd>silicate brick scrap</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>заполнители в бетон</kwd><kwd>бетонный лом</kwd><kwd>лом керамического кирпича</kwd><kwd>лом силикатного кирпича</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Akhmed AA.
