Введение. В статье приводятся результаты определения свойств слоистых пористых материалов, отобранных из глубины конструкций объектов культурного наследия, в той или иной степени подверженных долговременному воздействию влаги. Полученные данные сопоставляются со свойствами новых материалов, применяемых в аналогичных конструкциях и других объектах. Данные о новых материалах получены из литературных источников.

Цель

Цель. Выявление признаков изменения свойств слоистых пористых материалов, происходящих не только в поверхностном слое, но и по всей глубине конструкции.

Материалы и методы

Материалы и методы. Представленные исследования получены на основе результатов проведенных автором испытаний более 2500 образцов материалов из 24 памятников архитектуры разного времени и локаций, находящихся под долговременным влиянием неблагоприятных эксплуатационных факторов.

Результаты

Результаты. Полученные результаты показывают, что, в отличие от однородных материалов, разрушение слоистых систем происходит не послойно, начиная с поверхности, а одновременно во всем объеме конструкции.

Выводы

Выводы. Существенное изменение свойств материалов на всех исследованных участках показывает, что, в отличие от однородных материалов, разрушение слоистых систем происходит не послойно, а в объеме всей глубины конструкции.

Introduction

Introduction. The article presents the results of determining the properties of layered porous materials selected from the depths of the structures of cultural heritage sites, which are more or less susceptible to long-term exposure to moisture. The obtained data are compared with the properties of new materials used in similar structures and other objects according to literary sources.

Aim

Aim. Identification of signs of changes in the properties of layered porous materials occurring not only in the surface layer, but also throughout the entire depth of the structure.

Materials and methods

Materials and methods. The presented studies are based on the results of the author's tests of more than 2,500 samples of materials from 24 architectural monuments of different times and locations that are under the long-term influence of adverse operational factors.

Results

Results. The results show that, unlike homogeneous materials, the destruction of layered systems does not occur in layers, starting from the surface, but simultaneously throughout the entire volume of the structure.

Conclusions

Conclusions. A significant change in the properties of materials in all studied areas shows that, unlike homogeneous materials, the destruction of layered systems does not occur in layers, but in the volume of the entire depth of the structure.
