Jul 11, 2020  The soundness of cement is affected by the presence of excess lime and magnesia. The excess lime hydrates very slowly to form slaked lime and will affect the physical properties of cement. The hydration difference between free lime (CaO) and slaked lime can change the volume of concrete on hardening and these changes make cement unsound.
