Gypsum (4 to 5%) is added to regulate the setting time of the cement. These raw materials (Table 10.3) are finely ground, mixed, and heated (burned) in a rotary kiln to form cement clinker. Table 10.4 lists the predominant compounds that are formed during calcining. The cement industry uses the following abbreviations for these clinker compounds:

ADVERTISEMENTS: Portland cement can be manufactured by intimately mixing together calcareous and argillaceous stones containing silica, alumina, and iron oxide etc. and burning it in large rotary kilns at a temperature of approximately 1400C to 1500C. At his temperature the materials partially fuse, forming clinker. This clinker is cooled and ground to fine power. Usually []
