Types of Cement - الرئيسية

2.1 Ultra High Early Strength Cement The rapid strength development of this type of cement is achieved by grinding the cement to a very high fineness: 700 to 900 m2 /Kg. Because of this, the gypsum content has to be higher (4 percent expressed as SO3). Because of its high fineness, it has a low bulk density.
