Is using GGBS in concrete more expensive?

Using Ground Granulated Blast Furnace Slag (GGBS) in concrete can be more expensive than traditional Portland cement due to the higher cost of the material and the processing involved. However, GGBS can enhance the durability and longevity of concrete, potentially leading to lower maintenance and lifecycle costs. Additionally, its use may be incentivized by sustainability goals, offsetting initial costs over time. Ultimately, the economic impact depends on project specifications and local material availability.
