Sulfate Attack on the Cation Type Accompanying $SO_4^{2-}$

This paper reports a study carried out to investigate sulfate attack caused by cation type(sodium, magnesium) accompanying $SO_4^{2-}$ ions in sulfate solutions. The sulfate attack of mortar specimens was evaluate using the visual appearance, compressive strength loss and expansion. In addition, at the end of 360 days, the products of sulfate attack and the mechanism of attack were investigated through x-ray diffraction.
