Effects of cement fineness on cement properties
A. Increasing the fineness increases the rate of hydration of cement, which increases the rate of gain in strength and also the rate at which heat is liberated as in Type III compared with Type I cement (ASTM C150). Increasing the fineness of a cement also increases the amount of mixing water required to achieve a given consistency and reduces

Fineness of Cement and Concrete Quality
A.: The fineness of cement usually affects the rate at which cement gains strength. It may also have a minor effect on workability but probably not much. If you took a cement and ground part of it to a greater fineness the finer portion would produce higher early strength than the other portion. Fineness cannot by itself, however, be taken as
