Abstract In this paper, the effects of different mineral admixtures and sulfate solution types on the appearance, mass
change rate, relative dynamic elastic modulus, and corrosion resistance coefficient of concrete were systematically
studied. X-ray Diffraction (XRD), Mercury Intrusion Porosimetry (MIP), Scanning Electron Microscopy (SEM),
and X-ray Computed Tomography (X-CT) were used to explore and analyze the changes in the microstructure
and the corrosion products of concrete in the sulfate solution. The results show that the existence of magnesium
ions accelerates concrete deterioration. There is a critical dosage of fly ash for magnesium sulfate resistance of
concrete. The magnesium sulfate resistance of… More >
