Abstract

Damage to brick walls and facing stone materials caused by soluble salts is described. Chemical and physicochemical factors that cause salt corrosion of brick and brickwork of building structures are considered. Chemical reactions of the formation of crystals that cause corrosion in ceramic bricks are given. The conditions for the appearance of efflorescences on brickwork are generalized. Results of studies of salt corrosion of brick walls of buildings for various purposes, results of studies of water extracts from various ceramic raw materials and their analysis are presented. General recommendations for the prevention and elimination of efflorescence on the surfaces of brick walls of buildings and building structures are given.

Key words:

humidity of brick, salt corrosion; inspection of building, defects of stonework
