description: Theme of final qualifying work: "The durability of concrete structures when exposed to moisture and alternating temperatures, and the protection of hydrophobic compounds."
This work is devoted to the study of the dependence of concrete durability when exposed to moisture and alternating temperatures on the characteristics of water resistance and frost resistance.
The aim of this research: Development of methods for predicting the durability of concrete structures operating in moisture and alternating temperatures in conditions.
The object of this research: Concrete structures working in moisture and alternating temperatures in conditions.
The subject of this research: Durability of concrete structures working in moisture and alternating temperature conditions.
The tasks that were set in this work:
1. Investigate the methods currently used to determine the durability of
structures, analyze the advantages and disadvantages of each of them, evaluate
the terms and conditions of their applicability;
2. Based on existing methods, form a methodology for determining durability,
which allows to reduce the error in determining the durability and its increase
after repair work.
3. Establishment of the dependence of frost resistance and water tightness on the
durability of concrete structures with the use of waterproofing compounds
operating at alternating temperature in humid conditions.
During the study, experimental studies were conducted to study the properties of
concrete and the phenomenon of self-healing cracks.
The practical significance of the work consists in the possibility of using
penetrating insulation as a tool not only for direct use - to increase the water resistance of concrete structures, but also to increase the frost resistance and durability of concrete, that is, a longer service life of structures. This will be followed by economic efficiency due to cost savings on scheduled repairs and maintenance.
During the study, the following results were obtained:

 ï­ In the presence of the Penetron Admix additive, concrete samples show a significant increase in the water resistance and resistance of concrete against corrosion and frost damage indicate a significant increase in the durability of structures.
ï­ Assessment of frost resistance of concrete by the loss of water resistance is more sensitive to violation of the structure of concrete than the assessment of strength, and can serve as a criterion of durability.
ï­ The calculation of economic efficiency showed a high service life (50 years) of concrete treated with low labor, organizational and operating costs.
Scientific novelty lies in the development of a method that allows to determine the degree of increase in the durability of structures in conditions of impaired waterproofing of structures of buildings and structures, as well as the composition of penetrating waterproofing, which can achieve the maximum effect.
