Resistance of concrete with granulated blast furnace slag ...

This paper explains that granulated blast furnace slag sand can improve the resistance of concrete to sulphuric acid attack. When a part of cement is replaced with ground granulated blast furnace slag, and the granulated blast furnace slag sand is used for sand, the resistance of concrete to sulphuric acid attack can be improved because a coating of gypsum (calcium sulfate dihydrate) is formed ...
