Is grading of cement important?

Particle size distribution of cement particles are maintained in such a way as to give a desirable grading pattern. Just as the good grading of aggregates is essential for making good concrete, it is widely agreed that good grading pattern of cement particles is also important.

Unfortunately we still are not sure as to what a “good grading” of cement means i.e should all the particles be of the same size or should the size distribution of cement particles be so as to get a pack density.

Data obtained so far in this regard is rather confusing.
