Abstract


The results of experimental studies of the strength of the normal sections of rubcon-concrete two-layer bending building structures are presented in the paper.

Studies of two-layer rubcon-concrete bending structures were carried out in connection with the need for effective building structures, designed for use in corrosive media with reliable protection of steel reinforcement from the environment without special protective coatings (requiring repair during the operation).

As a result of studies, it was found that the strength of the normal sections of rubcon-concrete bending elements depends on the ratio of rubcon and concrete layer thicknesses, as well as the percentage of the longitudinal reinforcement. Thus, the strength of the normal sections increases with an increase in the reinforcement percentage and the rubcon layer thickness. It was found that with percentages of longitudinal reinforcement of up to 1.5%, failure occurs on the tension zone (on reinforcement), with percentages of longitudinal reinforcement higher than 1.5%, failure occurs on the compression zone (on concrete). It was revealed that with any reinforcement percentage and rubcon layer thickness, the strength of the normal sections of rubcon-concrete beams is higher than that of similar reinforced concrete.

The research results can be useful in the design and building of objects of the chemical and other industries, in which structures are exposed to various corrosive media. The developed structures allow to ensure reliable and durable operation of such buildings and facilities without overhauls for a longer period than the structures from conventional materials, such as reinforced concrete. Furthermore, the studied structures allow to save building materials since their carrying capacity is higher than that of analogs from conventional concrete.
