Also called Ground Granulated Blast-Furnace Slag (GGBFS)
Slag cement, or ground granulated blast-furnace slag (GGBFS), have improved durability characteristics that help further reduce life-cycle costs, lower maintenance costs and makes concrete more sustainable.
Using slag cement in addition to portland cement in a concrete mixture is a useful method to make concrete better and more consistent. Among the measurable improvements are:
Better concrete workability
Higher compressive and flexural strengths
Improved resistance to aggressive chemicals
More consistent plastic and hardened properties
Concrete containing ground granulated slag develops strength over a longer period, leading to reduced permeability and better durability. Since the unit volume of Portland cement is reduced, this concrete is less vulnerable to alkali-silica and sulfate attack. Other uses include GGBS cement, Soil cement, Roller compacted concrete, Road Base, Agriculture/Soil Amendment, and Glass Manufacture.
