Clinker Production - Clinker Manufacturing | Cement
What is the cement clinker? As we know, the cement production process is mainly divided into raw material preparation, clinker calcination, and cement grinding. Clinker is the material produced in the calcination stage and is usually used as the binder in many cement products. In other words, it is a semi-finished cement product by preparing ...

Since building value can be related to cement strength the
Since building value can be related to cement strength the value for a tonne of cement could vary with a factor of two. Theoretically it would thus be possible for a cement company to reduce the percentage of clinker and the carbon emissions per tonne by lowering the quality. All companies elaborate on the use of alternative fuels and plans for increasing the percentage.

Future of Cement: Low-Carbon Technologies and Sustainable
May 15, 2020 · Reducing the clinker factor: The average clinker to cement ratio is called the clinker factor and the 2014 global average clinker ratio of 0.65 needs to be reduced to 0.6 by 2050 to meet the Paris goals . This can be lowered by substituting some of the clinker with alternative materials such as fly ash, limestone or slag.
What is Cement Clinker? Composition, Types & Uses - Civil
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
Cement Production - an overview | ScienceDirect Topics
Shifting the cement production from wet to dry with preheating and precalciner kilns can lead to a reduction of 20% (International Energy Agency, 2010) of the energy needed and 17% in the amount of CO 2 emitted per tonne of clinker (Damtoft et al., 2008).
Solidia Cement an example of Carbon Capture and Utilization
cement industry accounts for approximately 5% of global anthropogenic carbon dioxide (CO 2) emissions. A modern cement plant releases ~810 kg of CO 2 per tonne of cement clinker produced. More than 60% of this CO 2 comes from the chemical decomposition, or calcination, of limestone (CaCO 3 → CaO + CO 2
