cement plant reduces its dust emissions

Alternative Clinker Technologies for Reducing Carbon Emissions …

Even though this is a promising cement, its application and use are limited, since its curing process must be conducted under very controlled CO 2 concentration conditions, which, so far, can only be provided in a ready-mixed concrete plant impairing to some extent the generalized use of Solidia cement as a substitute of OPC.

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 …
