In laboratory tests ordinary concretes with high slag blastfurnace cements lead to a higher scaling in the first freeze-thaw cycles than Portland cement. This scaling ranges between 0.1 to 0.3mm cement grout from the surface. Afterwards the scaling rate decreases significantly. HPC with high slag blastfurnace cement does not show this effect.
