В частности, технология центрифугирования представляется довольно перспективной. Цель данной работы – провести оценку зависимости коэффициентов вариатропной эффективности центрифугированного бетона от зернового состава крупного плотного и объемного содержания крупного пористого заполнителей. Всего было изготовлено и испытано десять образцов кольцевого сечения. По результатам испытаний опытных образцов центрифугированного бетона с различными сочетаниями зернового состава крупного плотного и объемного содержания крупного пористого заполнителей были определены фактические значения интегральных и дифференциальных прочностных и деформативных характеристик бетона. Произведен расчет и анализ коэффициентов прочностной и деформативной вариатропной эффективности. Определены рациональный зерновой состав крупного плотного и оптимальное объемное содержание крупного пористого заполнителей, позволяющие получить центрифугированный бетон с усиленной вариатропией и наиболее эффективным коэффициентом вариатропной эффективности.</p></abstract><trans-abstract xml:lang="en"><p>Presently, developing and improving low-material, energy- and resource-intense technologies for manufacturing concrete and reinforced concrete products and structures have become a topical issue in the construction industry. Therefore, centrifugation technology is promising. In the present work, we assess the dependence of the variatropic efficiency factors of centrifuged concrete on the grain size composition and volumetric content of coarse dense and coarse porous fillers, respectively. Ten samples having an annular cross-section were manufactured and tested. Based on the test results of centrifuged concrete samples with various combinations of the grain size composition and volumetric content of coarse dense and coarse porous fillers, respectively, the actual values of its integral and differential strength and deformation characteristics were determined. The structural and stress-strain variatropic efficiency were calculated and analysed. The optimal grain size composition and volumetric content of the coarse dense and coarse porous fillers, respectively, were determined and allowed centrifuged concrete with an enhanced variatropy and optimum variatropic efficiency coefficient to be obtained.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коэффициент вариатропной эффективности</kwd><kwd>вариатропия</kwd><kwd>зерновой состав</kwd><kwd>прочность</kwd><kwd>деформативность</kwd><kwd>объемное содержание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coefficient of variatropic efficiency</kwd><kwd>variatropy</kwd><kwd>grain size composition</kwd><kwd>strength</kwd><kwd>deformability</kwd><kwd>volumetric content</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">Сулейманова Л.
