The cement clinker in these studies contained a small amount of CS, ranging from 0.3% to 2.5%, and possibly in combination with other waste materials such as ashes from sewage sludge, municipal incineration and coal combustion, sewage dry powder and aluminium dross that together amounted to around 8–40% of the total raw feed composition, as

Carbon Capture and Utilization by mineralization of cement

Reduction of CO 2 emissions associated with cement production is challenging in view of the increasing cement demand and the fact that major part of the emissions originates from the main raw material used limestone which can be only to extremely low amount substituted. A Carbon Capture and Utilization (CCU) approach based on mineralization of fines derived from concrete appears to be a

What is Cement Clinker? Composition, Types & Uses Civil

2021-8-23  Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.

Cement Analysis IEA

Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker production process.. From 2014 to 2018, the clinker-to-cement
