Panasiuk V. Structure and properties of hardening concrete long

The object of research - processes of formation of structure and properties of concrete as a material difficult to arrange in time; goal - definition of operational properties of the microstructure of concrete and concrete structures of various compositions and after long-term (8-37 years) hardening in vivo; methods - eperimental studies conducted standard and special methods using certified measurement devices and test equipment. The methods of qualitative and quantitative assessment of damage cement stone and concrete technological and operational defects, the definition of rational composition of the filler was carried out using experimental and statistical methods of experimental design; results - recommendations for the rational use of fillers to increase the fracture toughness of concrete with an increase in the mechanical characteristics and stability under repeated freezing and thawing; developed "Guidelines for Accounting humidity control of concrete strength by ultrasonic method"; introduced - in a number of engineering and construction companies in Odessa in the survey, design and construction of civil and industrial assets.
