Методы определения прочности в тонкостенных и тонкослойных конструкциях». Приведены решаемые в ходе разработки задачи, возможности и область применения положений стандарта на практике. Приводятся ссылки на первоисточники использованных в стандарте методик испытаний, особенности предъявляемых требований к испытательному оборудованию, общие принципиальные аспекты введенного в действие документа, предложения перспективного совершенствования поддерживающих стандартов.</p></abstract><trans-abstract xml:lang="en"><p>The article describes the peculiarities of the provisions of the new national standard GOST R 70307–2022 “Fine-grained concretes and mortars for construction. Methods for determination of strength in thin-walled and thin-layer structures”, developed in the Scientific Research Institute for Concrete and Reinforced Concrete (NIIZhB) named after A.A. Gvozdev – subdivision of JSC “SRC “CONSTRUCTION”. The tasks solved during standard’s development, opportunities and scope of application of the standard in practice are outlined. References to the primary sources of the test procedures used in the standard, peculiarities of the requirements to the test equipment, general principle aspects of the document put into effect, and proposals for prospective improvement of the supporting standards are given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>испытания</kwd><kwd>бетон</kwd><kwd>раствор</kwd><kwd>тонкослойные покрытия</kwd><kwd>тонкостенные изделия и конструкции</kwd><kwd>контроль качества</kwd><kwd>контрольные образцы из конструкций</kwd><kwd>испытания штампом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tests</kwd><kwd>concrete</kwd><kwd>mortar</kwd><kwd>thin-layer coatings</kwd><kwd>thin-walled products and structures</kwd><kwd>quality control</kwd><kwd>test specimens from structures</kwd><kwd>stamping tests</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">СН 290-74 «Инструкция по приготовлению и применению строительных растворов».
