(57) The object of the invention is a method and an apparatus for manufacturing cement, in which method additives and/or agents, such as fly ash, the particles (21) of which are smaller in grain size than the cement particles (22) of the cement powder, are added to ground clinker material. In conjunction with the cement manufacturing process, fly ash precisely graded by grain size is added to the cement powder ground from clinker material after grinding, said fly ash comprising approx. 20-80 % essentially round fly ash particles.
