Pазработка газобетонов с повышенным содержанием открытых пор, с применением полиминеральных вяжущих со сниженной цементоемкостью и значительной утилизацией местных техногенных ресурсов (в частности обогащенных отходов предприятий теплоэнергетики) актуальна для современной строительной индустрии. Для систематизации современных методов изучения характеристик звукоизоляции и звукозащиты зданий необходимо учитывать многообразие международных строительных норм. Целью работы является освоение научно обоснованного технологического решения, обеспечивающего получение эффективных газобетонов на основе золы-уноса Китая с улучшенными звукопоглощающими характеристиками.Материалы и методы. В данной работе использована методологическая основа, которая предусматривает всестороннее использование фундаментальных подходов в строительном материаловедении. Для разработки композиционных материалов заданного качества на нано-, микро- и макроуровнях было применено комплексное проектирование. Физико-механические свойства сырья и требуемые характеристики разработанных материалов изучались с использованием физико-химических методов анализа, включая лазерную гранулометрию, рентгенофазовый анализ, электронную сканирующую микроскопию, термические методы и т.д. Экспериментальные исследования проведены в лабораториях БГТУ им. В.Г. Шухова, а также китайских университетах.Заключение. В данной работе были сформулированы научные подходы для проектирования и синтеза газобетонов с улучшенными акустическими характеристиками в различных регионах страны, с учетом местного сырья. Дальнейшие исследования могут быть направлены на расширение ассортимента лег ких материалов для ограждающих конструкций с целью обеспечения безопасной среды обитания человека. Это может быть достигнуто путем синтеза многокомпонентных композиционных вяжущих, которые влияют на формирование нано-, микро- и макроструктуры материалов.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. The development of aerated concrete with a high content of open pores, using polymineral binders with reduced cement content and significant utilization of local technogenic resources (in particular, enriched waste from thermal power plants) is relevant for the modern construction industry. To systematize modern methods for studying the characteristics of sound insulation and sound protection of buildings, it is necessary to take into account the diversity of international building codes. The aim of the work is to develop a scientifically based technological solution that provides effective aerated concrete based on fly ash from China with improved sound-absorbing characteristics.Main part. In this paper, a methodological basis, which provides for the comprehensive use of fundamental approaches in building materials science, was used. Integrated design to develop composite materials of a given quality at the nano-, micro- and macrolevels was used. The physical and mechanical properties of raw materials and the required characteristics of the developed materials using physicochemical methods of analysis, including laser granulometry, X-ray phase analysis, scanning electron microscopy, thermal methods, etc were studied. The experimental studies in the laboratories of V.G. Shukhov BSTU, as well as Chinese universities were carried out.Conclusions. In this work, scientific approaches for the design and synthesis of aerated concrete with improved acoustic characteristics in various regions of the country, taking into account local raw materials were formulated. Further research can be aimed at expanding the range of lightweight materials for building envelopes in order to ensure a safe human environment. This can be achieved by synthesizing multicomponent composite binders that affect the formation of nano-, micro- and macrostructures of materials.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>строительство</kwd><kwd>материаловедение</kwd><kwd>сооружение</kwd><kwd>изоляция</kwd><kwd>шум</kwd><kwd>композит</kwd><kwd>уровень звука</kwd><kwd>человек</kwd><kwd>газобетон</kwd><kwd>ячеистый бетон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>construction</kwd><kwd>materials science</kwd><kwd>structure</kwd><kwd>insulation</kwd><kwd>noise</kwd><kwd>composite</kwd><kwd>sound level</kwd><kwd>man</kwd><kwd>aerated concrete</kwd><kwd>cellular concrete</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Harding J.
