Сахалин. Показано, что отсутствие методов прогнозирования коррозии бетона в условиях морозного воздействия, обусловлено многообразием и синергетическим эффектом факторов, определяющих долговечность. Многоцикличное воздействие знакопеременных температур, обусловленное морскими приливами, не всегда является определяющим критическим показателем суровости для зоны переменного уровня. Незамерзающая вода в акватории портов и тяжелые гидрометеорологические условия в виде сильного волнения предопределяют обледенение конструкций в течение всего зимнего периода. Этот фактор в определенных случаях может являться критическим для бетона. На основании результатов исследования состояния, свойств и температурно-влажностного режима бетона в конструкциях зоны переменного уровня воды и общепринятых теоретических положений морозного разрушения бетона предложено прогнозировать срок службы в зоне переменного уровня портовых сооружений на основе концепции двухстадийности процесса морозной коррозии. Показана возможность прогноза долговечности бетона на основе сценарного моделирования процесса развития системы структуры пор цементной матрицы в зависимости от ее параметров к началу морозного воздействия и механизма промерзания бетона в конструкциях.</p></abstract><trans-abstract xml:lang="en"><p>A conceptual approach is presented to predicting the durability of concrete under conditions of frost exposure and strong saturation based on the actual work of concrete in the structures of port facilities on the sea coast of the south of the island. Sakhalin. It is shown that the lack of methods for predicting concrete corrosion under frost exposure, despite the large amount of theoretical and experimental work on this topic, is due to the diversity and synergistic effect of factors that determine durability. It has been established that the multicyclic effect of sign-variable temperatures due to sea tides is not always the determining critical indicator of severity for the zone of variable level. Non-freezing water in the port waters and severe hydrometeorological conditions in the form of strong waves predetermine the icing of structures throughout the winter period. This factor in certain cases can be critical for concrete. Based on the results of the study of the state, properties and temperature-humidity regime of concrete in the structures of the zone of variable water level and the generally accepted theoretical principles of frost destruction of concrete, it is proposed to predict its service life in the zone of variable level of port facilities based on the concept of a two-stage process of frost corrosion. The possibility of predicting the durability of concrete based on scenario modeling of the process of development of the system of pore structure of the cement matrix, depending on its parameters by the beginning of frost exposure and the mechanism of freezing of concrete in structures, is shown.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>водонасыщение бетона</kwd><kwd>долговечность</kwd><kwd>морозостойкость</kwd><kwd>морские сооружения</kwd><kwd>срок службы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>concrete water saturation</kwd><kwd>durability</kwd><kwd>frost resistance</kwd><kwd>offshore structures</kwd><kwd>service life prediction</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">Performance-Based Specifications and Control of Concrete Durability: State-of-the-Art Report RILEM TC 230-PSC (RILEM State-of-the-Art Reports (18), Springer; 1st ed. 2016, (October 3, 2015), 391 p.</mixed-citation><mixed-citation xml:lang="en">Performance-Based Specifications and Control of Concrete Durability: State-of-the-Art Report RILEM TC 230-PSC (RILEM State-of-the-Art Reports (18), Springer; 1st ed. 2016, (October 3, 2015), 391 p.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Карпенко Н.И., Ярмаковский В.Н., Ерофеев В.Т.
