Olekseenko E. Performance Properties and durability of structures facade insulation with a thin layer plaster

The object - is an operation of wall constructions facade thermo-insulation with thin-layer plaster;the aim - is the development of methodology for the evaluation of performance indicators and durability of structural facade thermo-insulation with finishing plasters and the establishment of their thermophysical properties; methods - analytical and experimental methods of the investigation ofthermal indicators of enclosing structures, methods of statistical analysis of the influence of random factors;novelty- received further development of criteria determination and methodological provisions of evaluating performance and durability of structural facade thermo-insulation and; the properties influenceof a finishing layer of integrated thermal parameters of constructions characteristic of the destructive factors and causes of thermal failuresdetermined; for the first time it was carried out the experimental investigations of the dynamics of the crack decorative plaster layer facade system depending on changes of environmental parameters and temperature deformations of heat-insulating materials; it was received further development of experimental researches by the definition of the stability indicatorsof constructions of the facade insulation to climate impacts given the variability of the physical-mechanical properties of defects, damages, loads and impacts on them and thermal reliability of structures, subject to reliability; received a further development of laboratory and theoretical studies of thermal deformations of heat-insulating materials facade thermo-insulation with thin-layer plaster; improved mathematical model and algorithm of calculation of the temperature and humidity of facade system with given the annual cycle of exploitation; results - research methods and criteria for evaluation of performance of structures facade thermo-insulation indicators of thermal reliability and energy efficiencywere developed; suggested methods and recommendations for the forecasting of the crack dynamics of a plaster layer facade thermo-insulation empirical formulas; carried out the determination of the term of effective exploitation of facade insulation research of the constructions stability to climatic influences, made a calculation of the temperature deformations of broken plaster and thermal insulation materials; improved mathematical model of calculation of temperature-humidity conditions of enclosing structures that can predict the thermal and humidity state of the facade thermo-insulation for each month of the year;field-building construction.
