The problem of restoring the facades of historic buildings is very relevant throughout the world. Physical wear and tear of materials and damage to facades are caused by climatic factors and environmental pollution. Romanesque cement is typically used for architectural and decorative elements of facades of stone buildings from the second half of the 19th century to the early 20th century in Europe, particularly in Lviv. Depending on the type of decorative and structural elements, the methods of their manufacture, reinforcement, and placement on the facade differ. This affects the state of preservation and the processes of destruction.
The article also discusses the possibilities of using high-quality concrete for the restoration and creation of sculptures on the facades of historic buildings. The composition of the mixture provides a high level of technological performance, a self-compacting effect, and the possibility of perfectly reproducing small elements during restoration work. Laboratory tests of samples confirmed high mechanical strength, low water absorption, and increased frost resistance. The sculptural elements have a perfect surface and shape and promise to be more durable compared to production technology using traditional cement and lime mortar.
