Clinker: combinability of mixes
Clinker composition is evidently one of the key factors which determine cement quality. Composition is controlled mainly by suitable blending of raw materials, but there are limitations to what can be achieved. Before considering these limitations, a summary of the clinkering process, and of the role of the liquid phase, may be useful. The essential reactions in making Portland cement are the ...

The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to preblending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly ash) are added to get the desired chemical composition ...
Can the global cement industry cut its carbon emissions?
· Cement is responsible for around 7% of global carbon emissions. If the cement industry were a country then it would be the largest carbon emitter after China and the US. To be in line with the Paris Agreement, the cement industry must reduce its annual carbon emissions by at least 16% by 2030, according to a report published by UK thinktank ...
Decarbonisation options for the Dutch cement industry
Section 1 introduces the Dutch cement industry. Section 2 describes the current situation for cement production processes in the Netherlands, and Section 3 describes the relevant products of these processes, while options for decarbonisation are systematically quantified and evaluated in Section 4. The feasibility of and requirements for those ...

Laying the foundation for a zerocarbon cement industry ...
· Clinker substitution. CO 2 emissions are directly proportionate to the amount of clinker used in cement production. Therefore, clinker can be substituted by cementitious materials such as natural and calcined pozzolans, as well as industrial byproducts such as fly ash and blast furnace slag. Similarly, the use of pozzolans depends on their ...
Clinkerization
With the development of cement technology, 60% of the fuel required is fired in calciner and 90 to 95 % of calcination duty is done outside the kiln. Development of Calciner have been a great boon in multiple ways to Cement Industry like: Burning is more uniform and hence clinker .
