Cement – Analysis - IEA

From 2014 to 2018, the clinker-to-cement ratio increased at an average of 1.6% per year, reaching an estimated 0.70 in 2018; this rise was the main reason for the increase in direct CO 2 intensity of cement production over the period.

Cement Clinker Calcination in Cement Production Process ...

04-04-2019  The cement clinker calcination is an important step in the cement production process. It mainly occurs in cement kiln and can be roughly divided into six reaction stages, namely drying, preheating, chemical decomposition, exothermic reaction, sintering and cooling.

The effort in reducing the amount of clinker in cement is progressing well and the clinker to cement ratio has been reduced to 76,4%. The uncertain sustainable availability of clinker substitutes is the main constraint. CEMBUREAU has projected the clinker to cement ratio at 70% by 2050.

Global 2 emissions from cement production

For China, which currently produces almost 60% of global cement, clinker production data are available from 1990. China’s emission factor is reported by NDRC (2014) as 0.5383tCO2(tclinker)1, and this is used both in the second national communication (NDRC, 2012)

Cement kiln - Wikipedia

Portland cement clinker was first made (in 1825) in a modified form of the traditional static lime kiln. The basic, egg-cup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker.

The direct CO2 intensity of cement production increased 0.5% per year during 2014-18. To get on track with the SDS, a 0.8% annual decline is necessary to 2030. Sharper focus is needed in two key areas: reducing the clinker-to-cement ratio (including through greater uptake of blended cements) and deploying innovative technologies (including CCUS).

Clinker Substitution - Cembureau

A global clinker-to-cement ratio of 78% in 2006 meant that about 550-600 million tonnes of constituents other than clinker were used. The International Energy Agency (IEA) 2 estimated that in 2005, there were around 1,215 million tonnes of material suitable for clinker substitution globally (excluding pozzolan and limestone).

Emissions from the Cement Industry - State of the Planet

09-05-2012  Though “cement” and “concrete” are often used interchangeably, concrete is actually the final product made from cement. The primary component of cement is limestone. To produce cement, limestone and other clay-like materials are heated in a kiln at 1400°C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement.
