Korobko O. Formation of interdependent multi-level structures of building composites

The object of research - the structure of concrete and the structure of product as open self-organizing systems; goal - the development of experimental and theoretical foundations of the directional structure formation of interdependent different-scale structures of building composites for increase their resistance in difficult operating conditions; methods - testing of building composites carried out in accordance with the State standards of Ukraine and specially developed techniques; statistical analysis of experimental results is conducted using the apparatus of mathematical experiment planning; results – the methods of activation of processes of structure organization of cement and polymeric compositions, that contribute to the improvement of the quality of materials, are defined, warehouses of concretes with the increased resistance under low-cycle fatigue are recommended; novelty of the thesis - the scientifically grounded role of the interdependent organization of the multi-level structure of concrete in ensuring the structural design and functional properties of the product, the organization of the macrostructure as the interconnected set of multivariate substructures are analyzed and the influence of their parameters on the structure formation and properties of the matrix material and concrete is investigated; mechanisms for the participation of endo- and exodeformations in the formation of a multi-scale concrete structure and self-initiation of the development of deformation phenomena are proposed, the dominant role of inner surfaces of partition and cracks as the network of active elements in the structural adaptation of concrete to the operating environment is defined; proved the possibility of increasing the values of the properties of concrete and resistance of building products under the action of periodic external influences by directed increase in structural variety; introduced – to recommended for implementation in the production of cement products, the device of polymeric coverings, at construction of the monolithic objects and for repair and restoration operations in the building organizations of Odessa, as well as to educational process of OSACEA at the training of students of higher education in field of study 19 - Architecture and construction.
