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.

The filament winding method is one of the most efficient technologies for manufacturing composite structures with high strength-to-weight ratios. Traditionally, this process has been widely used for the production of axisymmetric structures such as pressure vessels, pipes, and cylindrical shells. However, modern aerospace and mechanical engineering increasingly require the production of composite structures with complex geometries, including prismatic and frame-type elements.
