Abstract
A calculation method for service life of concrete in a plateau environment considering protection and restoration effects is provided and includes a construction of a model based on a coupling effect of multi-factors of temperature-humidity-salt concentration-load under the plateau environment, simulation of protection and restoration effects, and quantification of service life. The model includes the physical fields of temperature conduction with variable boundary conditions, water dry-wet cycle transport, salt ion transport, and force fields caused by internal and external loads. The simulation of protection and restoration effects include: surface protective coating, damage restoration, and rebar corrosion resistance. The calculation method can simulate the internal temperature, humidity, stress response, and service life of concrete under different plateau environments using the surface protective coating, damage restoration material, and rebar corrosion resistance material, or a combination of protective and damage restoration materials simultaneously.
