The article is devoted to a comprehensive study of the use and condition of decorative elements made of Roman cement in the architecture of Lviv from 1850 to 1914. The historical prerequisites for the widespread use of this material are examined. A review of key publications and studies is presented, highlighting the chemical and technological characteristics of Roman cement, problems in the synthesis of restoration binders, and techniques for removing molds from architectural ornamentation.

Фізико-механічні властивості модифікованих в’яжучих композицій на основі романцементу та гідравлічного вапна

The basic problems of development of restoration materials in Europe are considered. The basic ways of optimizing the binder compositions based on roman cement and hydraulic lime are presented and the technological parameters of formation of roman cement and hydraulic lime with marl and marlaceous limestone of Galicia are determined. The possibility of the use of additives- retarders of hydration of modified binders is showed and their influence on physical and mechanical properties of the studied compositions is established.
