global growth in cement production since 1990 occurred in China (van Oss, 2017). There are two aspects of cement production that result in emissions of CO2. The first is the chemical reaction involved in the production of the main component of cement, clinker, as carbonates (largely limestone, CaCO3) are decomposed
Cement Production and Manufacturing Process | Portland Cement Industry ... The produced granular form is called clinker. Then it is ground with 4% gypsum to obtain Portland cement. There are two main processes in manufacturing Portland cement. Wet method; ... Importance of gypsum in cement industry.
More efforts needed. From 2014 to 2016, the direct CO 2 intensity of cement showed little change, as thermal energy efficiency improvements were offset by a slight increase in the global clinkertocement ratio. To meet the IEA SDS objectives, the direct CO 2 intensity of cement needs to decline by % annually through to 2030, even as cement production is expected to grow.
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 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kiln. ...

Since we have to use cement in the future, how can we do to reduce the CO 2 emission and what is the future of cement? Efforts have been doing ever since decades ago in the cement industry and research community. On the one hand, cement plants nowadays burn (hazardous) waste, say, car tyres, as fuel to make cement.
On 7 July 2015, the Company announced International Cement Kazakhstan Pte. Ltd., an indirect whollyowned subsidiary of the Company, had entered into a jointventure agreement with Mr Nurzhan Shakirov for the construction of a cement plant in Almaty, Kazakhstan and thereafter, for the production and sales of cement.
Cement clinker dust (CKD) is a problematic waste derived from the cement industry which may cause some problems in clinkering kiln operations and cement performance. CDW has to be discarded despite its hydraulic properties due to high content of chlorine, sulphur and alkalis.
