Therefore, the content of superfine cement has a great influence on its mechanical properties. When the superfine cement is not enough to fill the voids between the mineral admixtures, its hydration products are also difficult to bind all mineral admixtures tightly. Therefore, the mechanical properties of the hardened paste are low.
