ESSD - Global CO2 emissions from cement production, …

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.

Concrete’s carbon problem | Feature | Chemistry World

Cement accounts for 8 of global carbon dioxide emissions. Once cooled this mixture called clinker – is ground and gypsum calcium sulfate dihydrate added to improve the future setting of the cement. When water is added the silicates combine to form calcium silicate hydrate. This is the gel that binds the cement particles together.

History of cement

From the turn of the 20th century rotary cement kilns gradually replaced the original vertical shaft kilns used originally for making lime. Rotary kilns heat the clinker mainly by radiative heat transfer and this is more efficient at higher temperatures enabling higher burning temperatures to be achieved.

The History of Concrete | Giatec Scientific Inc.

Jul 28 2017 This rekindled interest in building with concrete. It wasn’t until 1793 that the technology took a big leap forward when John Smeaton discovered a more modern method for producing hydraulic lime for cement. He used limestone containing clay that was fired until it turned into clinker which was then ground into powder.

Jun 09 2020 Cement production is currently the largest single industrial emitter of CO2 accounting for ∼8 2.8 Gtonsy of global CO2 emissions. Deep decarbonization of cement manufacturing will require remediation of both the CO2 emissions due to the decomposition of CaCO3 to CaO and that due to combustion of fossil fuels primarily coal in calcining ∼900 C and sintering ∼1450 C.
