The research on cement fineness has been ongoing since the production of cement, and has been continuously deepened based on the understanding of the properties of cement concrete.
Recently, I heard a new term on a concrete forum called “Grinding Universal Theory”.
Its main viewpoint is that materials such as cement and admixtures need to be ground, and the fineness of cementitious materials is too fine, which causes cracking in concrete.
No matter what material is ground in concrete, it can be used.
Whether the viewpoint is correct or not, it has aroused a lot of curiosity, as if the fineness of cement can be freely controlled.
