In a general cement, between 60 and 70% of the material should be between 3µm and 30µm in size. Excess large particles (greater than 50µm) can cause problems by reducing strength due to incomplete hydration, where as excess small particles (less than 2µm) can reduce strength and cause the cement to crack by setting exothermically.
