Abstract EN
The grey correlation theory and multiple regression method are used to reveal macro performance degradation rules of road concrete under loading and freeze-thaw and drying-wetting cycles; then the correlation between mesoscopic pore structure and residual strength and antifreezing index of concrete is analyzed.
Under the freeze-thaw and drying-wetting cycles with 50% loading level, the pore structure parameters that influence concrete strength show the following sequence: fractal dimension > most probable pore size > porosity > less harmful pore.
The correlation between strength and pore parameters can be represented with multiple nonlinear equations.
A negative correlation is shown between strength and fractal dimension and most probable pore size.
Conversely, a positive correlation is shown between strength, porosity, and less harmful pore.
Under the freeze-thaw and drying-wetting cycles with 80% loading level, the pore structure parameters that influence concrete strength show another sequence: fractal dimension > porosity > less harmful pore > most probable pore size.
The correlation between antifreezing index and pore parameters should be described with multiple linear equations.
The relative dynamic elastic modulus shows a positive correlation to most probable pore size, pore surface area, and porosity but a negative correlation to less harmful pore and pore spacing coefficient.
