Cement clinker, characterized in that it comprises Al2O3 and Fe2O3 wherein the mass ratio of Al2O3/Fe2O3 is 0.05-0.62, and alkali components and C2S wherein the content Y (mass %) of alkali components and the content X (mass %) of C2S satisfy the formula: 0.0025X+0.1≦Y≦0.01X+0.8. The production of the clinker allows the incorporation of alkali components into cement with an advantageous effect of enhancement of the hydration of belite and also with suppression of the lowering of flowability, which leads to the reuse of wastes containing alkali components as a cement raw material.

In a method for disposing of fibre cement waste products, in particular asbestos cement products, the products are simply coarsely crushed (less energy expended) and the resulting product is inserted in the entry zone of a revolving tubular kiln at a minimum temperature of 800 °C, preferably adding it to the normal stream for main materials used in cement production. The advantage lies in that, on the one hand, less energy is used and that, on the other hand, protection measures against fibres coming free whilst being coarsely crushed are easier to draw up than when crushing the products into a flour.

78 USE OF ORGANIC FIBRE CEMENT AS A RAW MATERIAL IN THE PRODUCTION OF CEMENT CLINKER EP13706931.6 2013-01-28 EP2807128A1 2014-12-03 SCHOON, Joris; VAN DER HEYDEN, Luc
Fiber cement material, which contains organic fibers, is used as an additional raw material for the production of cement clinker. The cement clinker is produced in a system which comprises a cyclone tower (11) and a rotating drum kiln (15). The cyclone tower (11) comprises cyclones (1-5) and a pre-calciner unit (10) wherein fuel is combusted to feed the cyclone tower with heat. The raw clinker meal is passed through the cyclone tower to preheat it. By the combustion of the fuel in the pre-calciner unit (10) a hot zone is produced in the cyclone tower wherein the raw clinker meal is calcined. In order to be able to add larger amounts of the fiber cement material without causing a too high total organic carbon content of the exhaust gasses and/or without causing depositions of organic matter onto the inner walls of the cyclone tower (11), the organic fiber cement material is added in a dry powdered form in said hot zone, in particular in the pre-calciner unit (10) to be heated in less than 5 seconds to a temperature of at least 800° C.
