Cement Clinker. Portland Cement. 1. 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. 2. Clinker is a granular substance containing spherical pellets of diameter 3-25 mm.

11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these
Cement accounts for 83% of total energy use in the production of non-metallic minerals and 94% of C02 emissions. Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process. Portland cement ...

Clinker produced by early static kilns and occurs in the form of large pumice like lumps or nodules. In the manufacture of Portland cement, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter and it is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminous silicate materials such as clay during the cement kiln stage.
Portland Pozzolana cement (PPC) is manufactured by the intergrinding of OPC clinker with 10 to 25 percent of pozzolanic material (as per the latest amendment, it is 15 to 35%). A pozzolanic material is essentially a siliceous or aluminous material which while in itself contains no cementitious properties, which will, in finely segregated form ...

We claim: 1. A process for the production of clinker containing alkali metal aluminate and dicalcium silicate from aluminous siliceous starting materials including the steps of mixing and grinding the aluminous siliceous starting material with at least one of the group consisting of calcareous correction materials and alkali metal-containing correction materials to a finely ground dry raw ...
The results were presented as graphs and tables. It was found that the ratio of aluminous cement to Portland cement most beneficial in terms of the setting rate of the resulting stucco mortar is 25% (m/m). This amount accelerates the end of setting time to 2 hours, the beginning of …
Clinker, when added with gypsum (to control the setting properties of cement and ensure compressive strength) and ground finely, produces cement. Clinker can be stored for long periods of time in a dry condition without degradation of quality, hence it is traded internationally and used by cement manufacturers when raw materials are found to be ...

The cooled, small-sized aluminous cement clinker is finely ground in suitable grinding installations according to EN 14647, point 5, usually without further additives. Ball mills in which grinding balls of different sizes crush the material to be ground in a rotating, cylindrical mill body by rolling and falling movements are generally suitable.
