The geometric characterization of bricks is essential for the standardization of materials and constructions and allows the design of structures with a higher degree of accuracy. This research, conducted in 12 provinces of the 3 continental regions of the country, where 79% of the buildings are concentrated, studies for the first time the geometric characteristics of solid clay bricks in Ecuador. The results show that 67% of the brick production in Ecuador is artisanal and 98% of the factories do not comply with the technical standards for brick production. The authors present the characteristic dimensions of solid bricks produced in different regions of Ecuador. The results show a high variation in brick dimensions depending on the region, and even in a same province the dimensions depend on the factory, since its production does not comply with any standard. Ecuadorian standards regulating brick geometry need to be updated taking into account the real characteristics of the national brick production.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">В Эквадоре около 95,9 % жилых домов построены из кирпичей, однако местное производство кирпича не соответствует техническим стандартам, отсутствуют научные исследования по его геометрическим характеристикам и техническому состоянию его производства. Определение геометрических характеристик кирпича имеет существенное значение для стандартизации материалов и конструкций и позволяет проектировать конструкции с более высокой степенью точности. В исследовании, проведенном в 12 провинциях трех континентальных регионов страны, где сосредоточено 79 % зданий, впервые изучаются геометрические характеристики полнотелого глиняного кирпича, произведенного в Эквадоре. Установлено, что 67 % производства кирпича в Эквадоре является кустарным и только 6 % - промышленным, при этом 98 % заводов не соблюдают технические стандарты производства кирпича и даже не знают об их существовании. Представлены характерные размеры полнотелого кирпича, произведенного в различных регионах Эквадора. Полученные результаты свидетельствуют о большом разбросе размеров кирпича в зависимости от региона, и даже в одной провинции размеры зависят от завода, поскольку производство не отвечает стандартам. Эквадорские стандарты, регламентирующие геометрию кирпича, нуждаются в обновлении с учетом реальных особенностей национального производства кирпича.</p></trans-abstract><kwd-group xml:lang="en"><kwd>clay bricks</kwd><kwd>geometric characteristics</kwd><kwd>solid brick dimensions</kwd><kwd>production technologies</kwd><kwd>masonry structures</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>керамический кирпич</kwd><kwd>геометрические характеристики</kwd><kwd>размеры полнотелого кирпича</kwd><kwd>технологии производства</kwd><kwd>каменные конструкции</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Love S.
