MODELING THE REINFORCEMENT CORROSION PROCESS IN REINFORCED CONCRETE STRUCTURE AT THE OBJECT OF TRANSPORT INFRASTRUCTURE
Annotation
To predict the safe state of reinforced concrete structures at transport infrastructure facilities, information on directions of crack opening in such structures is of principle importance. The cracks appearance is due to formation and increase in the amount of hydrated iron oxide (iron hydroxide) on the reinforcing bars, that is, caused by corrosion processes. Particularly dangerous are cases when reinforced concrete structures are manufactured in violation of the requirements. The paper considers a case of using steel reinforcement pins of different diameters. The presented results of calculations obtained using mathematical modeling of the nonlinear behavior of corrosion processes and the resulting deformation and structural destruction of concrete show the model forms and direction of crack opening.
