Slag cement, or ground granulated blast-furnace slag (GGBFS), is a recovered by-product of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design.
The use of slag cement has demonstrated long-term performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased durability.
Benefits of Slag Cement
- Improved workability, placement and finishing.
- Higher long-term compressive and flexural strengths.
- Reduced permeability.
- Improved durability and resilience.
- Lighter color.
- The use of slag cement in concrete can aid in achieving LEED points.
