Issues concerning the restoration of old brick buildings are examined. New compositions of high-performance dry construction mixes for restoration work are proposed. The results of physicochemical studies (x-ray structural and electron-microscopic analyses) of the initial fluoroanhydrite binder and the restoration dry construction mix obtained from it are presented. A list of technological operations involved in the restoration of the facades of brick buildings is presented.
