ESSD - Global CO2 emissions from cement production, 1928-2018

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.

Fly ash and pozzolanas - International Cement Review

A pozzolana is a material which, when mixed with a hydraulic cement, will react with the lime from the cement and water to produce cementitious hydration products of its own. The most familiar types of pozzolanic materials in common use are low-limed fly ash and silica fume, which are the residues from other industrial processes.
