A.I. Sagaydak belongs to the Russian scientific school of non-destructive testing of buildings and facilities that grew up at the R&D and Engineering Institute for Concrete and Reinforced Concrete under the leadership of Professor V.A. Klevtsov; he is a disciple of such renowned scientists and researchers of this field as S.I. Nogin and E.G. Nesvizhskiy; Mr.Sagaydak founded and continues heading an independent academic research field of "Quality control and monitoring of civil engineering structures through the acoustic emission (AE) procedures"; he developed a methodology for assessing the stress-strain status of structures and determining the pre-fracture condition of structures based on statistical parameters of the acoustic emission, as well as criteria for assessing the impact of defects on the bearing capacity of structures; the results of his research were incorporated in the technical standards and regulations for the civil engineering industry (MGSN, TU specifications, etc.); as Head of department of a private scientific and production company repeatedly implemented his ideas and developments in practice under public and private contracts for surveys of buildings and facilities; lectures within the system of advanced training and postgraduate education (State Academy of Investment Specialists, R&D and Engineering Institute for Concrete and Reinforced Concrete, R&D Institute for Civil Engineering in Moscow, etc.) with original materials on «Quality control of engineering structures", "Non-destructive testing using acoustic emission procedures"; forms part of the European working group on the acoustic emission procedures and of the RILEM Technical Committee; since the end of 1980s. - Participant and speaker (on the issue of acoustic emission) of the All-Union, All-Russian and international conferences of specialists and experts on non-destructive quality control;  

Publications: around 80 scientific and educational papers (1984-2014), including those included in research paper collections of R&D and Engineering Institute for Concrete and Reinforced Concrete, Moscow Civil Engineering Institute, St. Petersburg Transport Institute, and other universities and research centers, as well as in various conference proceedings.
