Our 2050 Roadmap
Low clinker cements. In 2017 the clinker to cement ratio in Europe was 77%. This means that, on average, 23% of clinker was substituted by alternative materials such as granulated slag from steel blast furnaces and fly ash from coal-fired power plants. The cement industry is conscious that the phase-out of coal fired power plants will limit the ...

What is Cement Clinker? Composition, Types & Uses
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. ...

Better and cheaper cement: Optimising the right clinker …
Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.
