This paper presents that granulated blast furnace slag sand can improve the resistance of concrete to sulfuric acid attack, sulfate attack and carbonation. When a part of cement is replaced with ground granulated blast furnace slag, and granulated blast furnace slag sand is used for sand, resistance of concrete to sulfuric acid attack can be improved more. Because, a coating of gypsum is formed on the mortar or concrete. A coating of gypsum is strong enough to prevent the corrosion by sulfuric acid attack.
