В связи с этим технология центрифугирования является довольно перспективной. Целью настоящего исследования является поиск возможностей рецептурного регулирования вариатропной структуры бетона, а также создание способов оценки этой вариатропии, выраженной в качественном и количественном аспектах. Всего было изготовлено и испытано семь базовых образцов кольцевого сечения. По результатам испытаний опытных образцов центрифугированного бетона с различным зерновым составом крупного заполнителя были определены фактические значения интегральных и дифференциальных прочностных и деформативных характеристик бетона. Произведен расчет и анализ коэффициентов прочностной и деформативной вариатропной эффективности. Определен оптимальный зерновой состав крупного заполнителя, позволяющий получить центрифугированный бетон с усиленной вариатропией и, как следствие, наиболее эффективным коэффициентом вариатропной эффективности. Определена перспектива дальнейших исследований в направлении усиления вариатропии центрифугированных бетонных и железобетонных изделий и конструкций путем регулирования рецептурно-технологических факторов.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>At present, developing and improving low-material, energyand resource-intense technologies to manufacture concrete and reinforced concrete products and structures have become a topical issue in the construction industry. Therefore, centrifugation technology is promising. In this article, the formulation of concrete with variatropic structure was improved, and the methods for its qualitative and quantitative assessment were developed. Seven annular cross-section reference samples were manufactured and tested. Based on the test results of centrifuged concrete samples with different grain size compositions of the coarse aggregate, the empirical values of the integral and differential strength and deformation characteristics of concrete were determined. The structural and stress-strain variational efficiency coefficients were calculated and analysed. The optimal grain size composition of the coarse aggregate was determined and allows centrifuged concrete with an enhanced variatropy to be obtained, as well as the most effective coefficient of variatropic efficiency. The prospects for further enhancing the variatropy of centrifuged and reinforced concrete products and structures by improving the formulationtechnological factors were determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>железобетонные изделия</kwd><kwd>центрифугированный бетон</kwd><kwd>вариатропия</kwd><kwd>прочностные характеристики</kwd><kwd>деформативные характеристики</kwd><kwd>зерновой состав</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reinforced concrete products</kwd><kwd>centrifuged concrete</kwd><kwd>variatropy</kwd><kwd>strength characteristics</kwd><kwd>deformation characteristics</kwd><kwd>grain size composition</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">Баженов Ю.М.
