Increasing the atmospheric resistance of plastering outside brick walls of heated buildings
Incoming article date: 18.03.2019Currently, in civil engineering, when building the exterior walls of buildings, plastered brickwork is most often used. The plaster gives the building a more aesthetic appearance, protects from weathering, moisture, precipitation. During the heating season, the plaster coating has the most destructive effect. Thus, the problem arises of the technology of plaster coating with a longer service life. The purpose of this research work was to study plaster on the external brick walls of heated civil buildings, as well as to find ways to improve the weather resistance of the facade plaster with the use of light stucco cement mortar and the use of advanced technology for its construction. To solve this problem, an analysis of the existing shortcomings of the facade plaster under atmospheric influences on it has been performed. Damage to the plaster layer arising during the process of atmospheric exposure is determined. In laboratory conditions, experimental studies were carried out to determine the optimum parameters of weatherproof plasters. The plaster coating of the external brick walls obtained by the above method has an increased strength, capable of resisting various atmospheric influences during the long-term operation of the heated building without degrading its functional properties.
