Specification of Clinker
The major raw material for the clinker-making is usually limestone mixed with a second material containing clay as a source of alumino-silicate.
An impure limestone containing clay or silicon dioxide (SiO2) can be used. The calcium carbonate (CaCO3) content of these limestones can be as low as 80% by weight.
Clinker is primarily used to produce cement. Since it can be stored in dry condition for several months without noticeable deterioration, it is traded internationally in large amounts.
Cement manufacturers buy clinker for their cement plants in areas where raw materials for cement are scarce or unavailable.
Uses. Portland cement clinker (abbreviated k in the European norms) is ground to a fine powder and used as the binder in many cement products.
Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat.
Clinker is a nodular material which is used as the binder in cement products. Cement is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. Clinker is a granular substance containing spherical pellets of diameter 3-25 mm.
