Production of slag cement creates a value-added product from a material—blast furnace slag.It also reduces air emissions at steel plants through the granulation process. Use of slag cement in concrete reduces the environmental impact of concrete by:
- Replacing the Portland cement by Slag helps in reducing CO2 emissions and in conserving non-renewable resources of lime stone.
- Reducing energy consumption, since a ton of slag cement requires nearly 90% less energy to produce than a ton of Portland cement.
- Reducing the amount of virgin material extracted to make concrete.
- Reducing the “urban heat island” effect by making concrete lighter in color thus reflecting more light and cooling structures and pavements with exposed concrete.
