Abstract. Global production of cement has grown very rapidly in recent years, and after fossil fuels and land-use change, it is the third-largest source of anthropogenic emissions of carbon dioxide. The availability of the required data for estimating emissions from global cement production is poor, and it has been recognised that some global estimates are significantly inflated.

About Cement Concrete : GCCA

Cement's central use is to bind together the ingredients of concrete – sand and aggregates. Cement is a glue, acting as a hydraulic binder, meaning it hardens when water is added. Cement itself is a fine powder that is made by first crushing and then heating limestone or chalk, with a few other natural materials, including clay or shale, added.

The CO2 intensity of cement production over that period has improved by about 7% (0.6t of CO2 emitted per tonne of cement in 2017) (2). By 2050, cement production in the EU is expected to remain below pre-2010 levels, ranging between 165Mt and 206Mt in the FORECAST model scenarios (4), which fed the industry analysis of the European Commission

Concrete and Cement Products

2021-2-23Portland cement is one of the basic materials in the construction industry. The principal component of Portland cement is clinker. According to the cement nomenclature, clinker contains two silicate phases: Ca 3 SiO 5 (alite) and Ca 2 SiO 4 (belite), as well as aluminate and ferrite. The alite to belite ratio is responsible for the strength of Portland cement in cement clinker.
