The effect of acid solution on the composition and microstructure of cement paste in concrete,and the mechanical properties of concrete specimens were studied by the rapid corrosion test,XRD and SEM analysis and the non-destructive test.Time-dependent model for change of mechanical properties subjected to environmental acid rain was proposed based on the rapid corrosion test and available environmental acid rain data.
