The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of

Portland Cement . Cement: is a material with adhesive and cohesive properties which make it capable of bonding minerals fragments into a compact whole. For constructional purposes, the meaning of the term quot;cementquot; is restricted to the bonding materials used with stones, sand, bricks, building stones, etc.
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 1400#176;C to 1500#176;C. At his temperature the materials partially fuse, forming clinker. This clinker is cooled and ground to fine power. Usually []
