Reabilitarea fațadelor clădirilor istorice din or. Chișinău cu piatră de calcar

Abstract

Most of the buildings of historical and architectural value in Moldova are made of limestone or brick. The facades are decorated with columns, half columns and pilasters, balusters, bas-reliefs and consoles. The dismantling of historic buildings over time leads to the need for renovation and restoration. Often privately owned buildings are repaired with modern materials without considering the original materials, without investigating the original elements and materials. Authentic decorative elements are being replaced by polyurethane foam elements which, due to their ease of installation and relatively low cost, can significantly reduce the financial cost of finishing and decorating facades. The interior walls of the brick are covered with plasterboard. Limestone exterior walls are plastered with cement mortar instead of lime mortar. The walls were partially covered with Styrofoam. All these substitutions reduce the architectural and historical value of the buildings and cause the loss of their authenticity. To preserve the value of historic buildings, it is necessary to use local materials. This research explores the possibilities of using limestone both for the restoration of masonry and for the restoration of decorative elements of 19th century.
