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 ...
