GBFS aka Steel Slag aka Water Slag has a hydraulic property and there is no risk of alkali-aggregate reaction. Because of the powerful latent hydraulic property that results from fine grinding, this slag is used in products such as Portland blast furnace slag cement. When blended with cement, the ground granulated blast furnace slag becomes Portland blast furnace slag cement with the same properties as ordinary (Portland) cement.

The advantages of this blast furnace slag cement, such as increasing strength over long periods of time, low heating speed when reacting with water, and high chemical durability, are put to effective use in a broad range of fields including in the construction of ports and harbors and other large civil engineering works.
