Clinker

Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, CO 2 is …

Cement

Cement emissions intensity has remained relatively stable since 2018, at just under 0.6 t CO 2 per tonne of cement produced, following several years of modest increase largely due to an increasing clinker-to-cement ratio in China. To get on track with the NZE Scenario, emissions must fall by an average of 3% annually through to 2030.

Glossary of terms

Cement constituents which are not derived from clinker production. They include blast furnace slag, fly ash, natural pozzolan and limestone. Ordinary Portland cement. Cement that consists of approximately 95% ground clinker and 5% gypsum. Ready-mix concrete. Concrete is a well-dosed mix of cement, aggregates, water and admixtures.

Q&A: Why cement emissions matter for climate change

Clinker can be substituted with other cement-like materials, including waste from coal combustion and steelmaking. This can affect the cement's properties, however, so is only suitable for some end uses. The world average clinker ratio (clinker:cement) fell to 0.65 in 2014, with a large range from 0.57 in China to 0.87 in Eurasia.

How Cement Is Made

After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects.

This CO2 saving is equivalent to a clinker factor of between 0.33-0.39 in a Portland cement-based system. Solidia Cement can potentially replace all of the Portland cement currently in use, as it can be made everywhere that Portland cement is made. With the broad replacement of Portland cement with Solidia Cement in North America alone,

Raw materials for cement manufacturing

Fast cooling of clinker (quenching) in cooler helps to freeze MgO in a glassy form which remains as it is and does not get hydrated to give expansion problem in cement paste. Alkalies: Some of the Na2O (Sodium oxide) and K2O (Potassium oxide) is built into the clinker menials C3A, C4AF and C4AF.Most of the remaining will remain water soluble.

Cement Clinker Manufacturing Process with Reactions

The principal reaction of this stage is as follows: Ca2SiO4 + CaO → Ca3SiO5. The liquid formed both acts as a solvent of ion exchange between the solid phases and draws the reactant particles together by surface tension. The powdery or granular mixture quickly solidifies into spherical nodules of 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. ...
