Toward electrochemical synthesis of cement—An electrolyzer .
Cement production is currently the largest single industrial emitter of CO2, accounting for ∼8% (2.8 Gtons/y) 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 (∼1,450 °C).

This reaction occurs throughout the depth of the well with the rate dependent on CO. 2
The Manufacture of Portland Cement
IX-Materials-B-Cement-1 THE MANUFACTURE OF PORTLAND CEMENT Cement is the substance which holds concrete together, which means that it is extremely widely used in our society. It has been manufactured in New Zealand for more than 100 years, and during this century production has increased one hundred-fold.
How Concrete is Made - Portland Cement Association
In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
