Optimization of Cement Sulfate

cement. Such factors include: • Sulfate becomes more effec-tive if interground (as compared to simple addition to cement) • The mill circuit in the fi eld is probably very different from the lab. This results in a different particle size distribution, and hence a different reactivity of the cement.
