По своим конструктивным особенностям данный материал является современным прототипом использовавшихся в строительстве с XIX века пустотелых кирпичей. Натурные исследования работы ограждающих конструкций с использованием пустотелых кирпичей показали, что во многих случаях кирпичи, уложенные в ограждающие конструкции зданий 60-80 лет назад подверглись существенному разрушению. При этом механизм разрушения не зависит от политермической нагрузки на материал. Выдвинутая гипотеза о том, что разрушение связано с химической деструкцией материала было исследовано с применением разработанной методики определения химической стойкости материала стеновой керамики. Проведенные исследования подтвердили выдвинутую гипотезу. Исследования химической стойкости материала крупноблочной пористой керамики должно быть учтено в технологии производства керамики.</p></abstract><trans-abstract xml:lang="en"><p>Large-block porous ceramics, which enter the market of building materials, have a number of undeniable qualities: low thermal conductivity, low density, high aesthetic qualities. According to its design features, this material is a modern prototype of hollow bricks used in construction since the nineteenth century. Field studies of the work of enclosing structures using hollow bricks have shown that in many cases, the bricks laid in the enclosing structures of buildings 60-80 years ago were significantly destroyed. In this case, the destruction mechanism does not depend on the polythermal load on the material. The hypothesis that the destruction is associated with the chemical destruction of the material was investigated using the developed method for determining the chemical resistance of the material of wall ceramics. The conducted studies confirmed the hypothesis. Studies of the chemical resistance of the material of large-block porous ceramics should be taken into account in the production technology of ceramics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крупноблочная пористая керамика</kwd><kwd>химическая деструкция материала</kwd><kwd>долговечность</kwd><kwd>лабораторные исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>large-block porous ceramics</kwd><kwd>chemical destruction of the material</kwd><kwd>durability</kwd><kwd>laboratory 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">Ищук М.К. «Отечественный опыт возведения зданий с наружными стенами из облегченной кладки».
