Sulfate corrosion is one of the main factors leading to a decrease in the durability of concrete structures.
After being corroded by sulfate, concrete usually undergoes deterioration phenomena such as expansion, cracking, and peeling.
The corrosive sulfate ions react with cement hydration products to produce gypsum and ettringite, leading to volume expansion and internal damage.
This study uses copper slag as an auxiliary cementitious material to replace some cement, and systematically evaluates its impact on the sulfate resistance of concrete.
