Resistance of chemically activated high phosphorous slag content cement against frost-salt attack

In the present work, durability performance of chemically activated high phosphorous slag content cement exposed to 1.5%, 3%, and 4.5% of deicing salt solutions along with repeated cycles of freezing and thawing was evaluated from mass loss, visual examination, XRD and SEM analyses of concrete test prisms. Concrete prisms of Portland cement of the same 28-day compressive strength class were also used as reference. The results confirm a significantly better resistance for chemically activated high phosphorous slag content cement against frost-salt attack.
