Slag is an industrial waste discharged during the iron-making process. Slag has “potential hydraulicity”, that is, it is basically non-hydraulic when it exists alone, but it becomes hydraulic under the action of certain activators (lime, clinker powder, alkali, gypsum, etc.).
The Use of Slag
Slag silicate cement is produced by mixing granulated blast furnace slag with silicate cement clinker and adding 3-5% gypsum, followed by fine grinding. This type of cement is particularly suitable for applications in marine engineering, harbor construction, and underground projects.
Slag can be used to manufacture slag bricks and wet-mill slag concrete products, which are popular in the market due to their unique properties.
By mixing water slag, activators (including cement, lime, and gypsum) in a roller mill and grinding them with water to form mortar, followed by mixing with coarse aggregate, wet-mill slag concrete can be produced, which has good molding properties.
Slag gravel concrete is a type of concrete made by mixing slag with gravel, and it has a wide range of applications in road and railway construction, favored for its excellent performance.
Expanded slag and expanded slag beads are primarily used as lightweight aggregates for the production of lightweight concrete. This type of concrete is widely used in the construction field due to its lightweight and high-strength characteristics.
