Slag Cement Production
Hardened concrete containing slag cement may show mottled green or blue-green areas a few days after placement, symptoms of a temporary condition known as "greening." SCIC #10, Greening, explains why the phenomenon happens, and explains that greening has no effect on the strength, durability and low permeability of slag cement concrete.
